Cryptography: The Science of Making and Breaking Codes

Cryptography: Crash Course Computer Science #33
 
12:33
Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself.

And I gotta bring pain in the Octagon When I wanna spit game at a soccermom I get it quicker than the left lane on the Autobahn; Fast— like Ramadan— and I battle young Padawans all the damn day I'm getting nekked and I'm hopping on a wrecking ball so hot I got that mothafucka a la flambé I go to Miley's house. I see that Miley's home. I play Miley's ribcage with my dick like it's a Xylie-phone Yes, that was highly fucked up but my skills are highly honed And if I was highly hyphy I might be more widely known C'est la vie.

As technology increases, so do the methods of encryption and decryption we have at our disposal. World War II saw wide use of various codes from substitution ciphers to employing Navajo code talkers in the Pacific theater. Here, science journalist and author Simon Singh demonstrates the German enigma machine, a typewriter-like device used to encrypt communications. He demonstrates not only its operation, but both the strength and fatal flaws in its method.

Keynote: Hacking is Child’s Play, Literally! - Reuben Paul, 11 Year Old Hacker, CyberShaolin Founder
 
22:07
Keynote: Hacking is Child’s Play, Literally! - Reuben Paul, 11 Year Old Hacker, CyberShaolin Founder and Cyber Security Ambassador  IoT is a buzz word but what does that mean? Internet of Things or Internet of Toys or Internet of Threats. In this keynote, 11 year old, Reuben Paul aka The Cyber Ninja would discuss and demonstrate how smart things (or toys) does not necessarily mean secure things. He will share his experience, playing with and hacking toys and cover tools (sniffers, packet analyzers, Raspberry Pi, python scripts) that could make connected systems creepy. With demonstration, he will highlight the insecurities in smart technologies and discuss the application of these technologies in the real world (drones, autonomous cars, etc.), and share why it is important to understand these threats that can not only impact things in a game room, but real things that we use daily as well. Come for a fun-filled, entertaining, and educational talk to find out how the hacking game is not limited just to the game room, and learn about why Hacking is Child’s play, literally! About Reuben Paul Reuben is a 11 year old from Pflugerville, TX. When asked by his 1st grade teacher to illustrate his future career, he drew on a sheet that he wanted to become a Cyber Spy. But, Reuben is not just another computer geek. He lives a life on the edge, between his school, as a straight ‘A’ student and all of his other passions. When he is not playing video games or on the computer, he likes to read, and takes classes to play inline hockey, swim, do gymnastics, Shaolin Do KungFu, play piano, drums and do art. Reuben is an invited speaker, delivering awareness talks and keynotes on the importance of teaching CyberSecurity to kids and adults. He has been featured at several industry leading Information Security conferences. His keynote talks on “Creating a Safe and Secure Cyber World for Kids (by a kid)”, “Developing r00t-kidz: The Future of Cybersecurity”, “InfoSec from the mouth of babes (or an 8 year old)”, and "Mutually symb-IoT-ic Security" have been quoted and referenced by several information security sources and news agencies that call him a “Child Hacker". They have become a source of inspiration to kids and adults alike to start teaching CyberSecurity to kids.

Ashoka the Great - Kings of India | History for Kids | Educational Videos by Mocomi
 
02:57
https://mocomi.com/ presents : The life of Ashoka Ashoka the great was emperor of the Maurya Dynasty who ruled the Indian subcontinent from 269 BC to 232 BC. His kingdom stretched from Pakistan and Afghanistan in the west to Bangaldesh and Assam in the east, and as far as Kerela and Andhra Pradesh in the East. Ashoka was headquartered in Magadha (Bihar). Ashoka in his younger days is said to have had a massive temper and was also very wicked and cruel. He once put his ministers through a loyalty test in which he killed 500 of them. He was also nicknamed Chand Ashoka which means ‘Ashoka the Fierce’ for having built a horrific torture chamber. On ascending the throne, Ashoka expanded his empire to regions in Iran, Persia and Afghanistan over the next eight years. The battle of Kalinga would be the one that would change his life forever. Kalinga was a rich and fertile land situated between the Godavari and Mahanadi rivers. This was the only land left to conquer. The people of Kalinga refused to bow down to Ashoka’s rule, however, they were also no match for Ashoka’s army. It is said that in this battle alone more than 100,000 soldiers lost their lives and many civilians who rose up in defense were deported.

CRYPTOGRAPHY | Secret Language  | CODING AND DECODING
 
03:07
CRYPTOGRAPHY | Secret Language | CODING AND DECODING When you were a kid, did you have a "Captain Midnight" decoder ring? With it, you could send messages to a friends that no one else could read. Or perhaps you remember using special symbols to write notes to your "squeeze" in class. If the note was intercepted , your teacher, could learn nothing about your romance. In more serious uses, codes and ciphers are used by our military and diplomatic forces to keep confidential information from unauthorized eyes. Businesses also send data that has been encoded to try and protect trade secrets and back-room deals. After all, you wouldn't want your competitor to know that you were about to acquire their company with a leveraged buy-out. The study of enciphering and encoding (on the sending end), and deciphering and decoding (on the receiving end) is called cryptography from the Greek κρυπτός (kryptos), or hidden and γράφειν (graphia), or writing. If you don't know Greek (and not many of us do) the above letters could be a form of code themselves! Although the distinction is fuzzy, ciphers are different from codes. When you substitute one word for another word or sentence, like using a foreign language dictionary, you are using a code. When you mix up or substitute existing letters, you are using a cipher. (I told you the difference was fuzzy, and you can combine codes and ciphers by substituting one word for another and then mixing up the result.) We'll concentrate on ciphers. For a cipher to be useful, several things must be known at both the sending and receiving ends. The algorithm or method used to encipher the original message (known as the plaintext). The key used with the algorithm to allow the plaintext to be both enciphered and deciphered. The period or time during which the key is valid. By way of analogy, to get into your home you would put a key in a lock to open the door. This process (the use of a key and a lock) is the method or algorithm. Now this method only works if you have the proper key to stick in the lock, and your key will be valid only as long as you are the resident of the particular abode. The next resident will have the locks changed to a different key to make sure that you cannot enter even though you may know the method. The selection of the above three items - algorithm, key and period - depend on your needs. If you are in the battlefield and are receiving current tactical data, you want an algorithm that makes it easy to decipher the message in the heat of battle. On the other hand, you must also assume that your opponent has intercepted your enciphered message and is busy trying to break it. Therefore you must choose an algorithm (method) that is complicated enough so that by the time your opponent figures it out, the data will be worthless. The easier the algorithm you choose, the more often you will have to change the key that unlocks the code - if you want to keep your enemy in the dark. Ciphers are broken into two main categories; substitution ciphers and transposition ciphers. Substitution ciphers replace letters in the plaintext with other letters or symbols, keeping the order in which the symbols fall the same. Transposition ciphers keep all of the original letters intact, but mix up their order. The resulting text of either enciphering method is called the ciphertext. Of course, you can use both methods, one after the other, to further confuse an unintended receiver as well. To get a feel for these methods, let's take a look at some ciphers. Substitution ciphers and decoder rings We use substitution ciphers all the time. (Actually, substitution ciphers could properly be called codes in most cases.) Morse code, shorthand, semaphore, and the ASCII code with which these characters are being stored in inside my Macintosh are all examples. (ASCII stands for American Standard Code for Information Interchange, just in case you're interested.) The only difference between these and the spy codes is that the above examples are standardized so that everyb

Cryptology vs. Cryptography
 
03:49
Students are often confused as to the difference between "cryptology" and "cryptography". To make matters worse, they often hear the term "cryptography" used incorrectly to mean cryptology. Technically speaking, Cryptology is the field that encompasses both Cryptography (code making) and Cryptanalysis (code breaking). However, people outside the field will use the term "cryptography" because "cryptology" just isn't a very well-known word. Our homepage: https://plaincipher.org
Symmetric Key and Public Key Encryption
 
06:45
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

What is an API?
 
03:25
What exactly is an API? Finally learn for yourself in this helpful video from MuleSoft, the API experts. https://www.mulesoft.com/platform/api The textbook definition goes something like this: “An application programming interface (API) is a set of routines, protocols, and tools for building software applications. An API expresses a software component in terms of its operations, inputs, outputs, and underlying types. An API defines functionalities that are independent of their respective implementations, which allows definitions and implementations to vary without compromising each other. A good API makes it easier to develop a program by providing all the building blocks. APIs often come in the form of a library that includes specifications for routines, data structures, object classes, and variables. In other cases, notably SOAP and REST services, an API is simply a specification of remote calls exposed to the API consumers. An API specification can take many forms, including an International Standard, such as POSIX, vendor documentation, such as the Microsoft Windows API, or the libraries of a programming language, e.g., the Standard Template Library in C++ or the Java APIs. An API differs from an application binary interface (ABI) in that an API is source code-based while an ABI is a binary interface. For instance POSIX is an API, while the Linux Standard Base provides an ABI”. To speak plainly, an API is the messenger that runs and delivers your request to the provider you’re requesting it from, and then delivers the response back to you. To give you a familiar example, think of an API as a waiter in a restaurant. Imagine you’re sitting at the table with a menu of choices to order from, and the kitchen is the provider who will fulfill your order. What’s missing is the critical link to communicate your order to the kitchen and deliver your food back to your table. That’s where the waiter (or API) comes in. ”AHEM” The waiter takes your order, delivers it to the kitchen, and then delivers the food (or response) back to you. (Hopefully without letting your order crash if designed correctly) Now that we’ve whetted your appetite, let’s apply this to a real API example. In keeping with our theme, let’s book a flight to a culinary capital – Paris. You’re probably familiar with the process of searching for airline flights online. Just like at a restaurant, you have a menu of options to choose from ( a dropdown menu in this case). You choose a departure city and date, a return city and date, cabin class, and other variables (like meal or seating, baggage or pet requests) In order to book your flight, you interact with the airline’s website to access the airline’s database to see if any seats are available on those dates, and what the cost might be based on certain variables. But, what if you are not using the airline’s website, which has direct access to the information? What if you are using online travel service that aggregates information from many different airlines? Just like a human interacts with the airline’s website to get that information, an application interacts with the airline’s API. The API is the interface that, like your helpful waiter, runs and and delivers the data from that online travel service to the airline’s systems over the Internet. It also then takes the airline’s response to your request and delivers right back to the online travel service . And through each step of the process it facilitates that interaction between the travel service and the airline’s systems - from seat selection to payment and booking. So now you can see that it’s APIs that make it possible for us all to use travel sites. They interface with with airlines’ APIs to gather information in order to present options back to us The same goes for all interactions between applications, data and devices - they all have API’s that allow computers to operate them, and that's what ultimately creates connectivity. API’s provide a standard way of accessing any application, data or device whether it is shopping from your phone, or accessing cloud applications at work. So, whenever you think of an API, just think of it as your waiter running back and forth between applications, databases and devices to deliver data and create the connectivity that puts the world at our fingertips. And whenever you think of creating an API, think MuleSoft.

DEF CON 23 - Robinson and Mitchell - Knocking my neighbors kids cruddy drone offline
 
47:34
My neighbor’s kid is constantly flying his quad copter outside my windows. I see the copter has a camera and I know the little sexed crazed monster has been snooping around the neighborhood. With all of the hype around geo-fencing and drones, this got me to wondering: Would it be possible to force a commercial quad copter to land by sending a low-level pulse directly to it along the frequencies used by GPS? Of course, radio signal jamming is illegal in the U.S and, frankly, it would disrupt my electronics, too. In this presentation, we’ll look at some of the research and issues we encountered, when we attempted to force land two commercial drones (the new DJI Phantom 3 and the Parrot Bepop Drone) by sending GPS signals directly at the drones (while staying under the threshold for jamming and not disrupting anyone else). Speaker Bio: Michael Robinson has over 15 years of computer security experience and is currently a computer and mobile device forensic examiner in the Washington, DC area, where he deals with intrusion analysis, incident response, and criminal cases. For over four years he ran IT and IA operations for a Department of Defense agency. He has conducted research on security of mobile devices and is starting to play around in the drone space. He teaches computer forensics at the graduate level at Stevenson University in Maryland.

Cybersecurity is a set of techniques to protect the secrecy, integrity, and availability of computer systems and data against threats. In today’s episode, we’re going to unpack these three goals and talk through some strategies we use like passwords, biometrics, and access privileges to keep our information as secure, but also as accessible as possible. From massive Denial of Service, or DDos attacks, to malware and brute force password cracking there are a lot of ways for hackers to gain access to your data, so we’ll also discuss some strategies like creating strong passwords, and using 2-factor authentication, to keep your information safe.

What is CRYPTOGRAPHIC SPLITTING? What does CRYPTOGRAPHIC SPLITTING mean?

What is CRYPTOGRAPHIC SPLITTING? What does CRYPTOGRAPHIC SPLITTING mean? CRYPTOGRAPHIC SPLITTING definition - CRYPTOGRAPHIC SPLITTING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Cryptographic splitting, also known as cryptographic bit splitting or cryptographic data splitting, is a technique for securing data over a computer network. The technique involves encrypting data, splitting the encrypted data into smaller data units, distributing those smaller units to different storage locations, and then further encrypting the data at its new location. With this process, the data is protected from security breaches, because even if an intruder is able to retrieve and decrypt one data unit, the information would be useless unless it can be combined with decrypted data units from the other locations. The technology was filed for patent consideration in June 2003, and the patent was granted in June 2008. Cryptographic splitting utilizes a combination of different algorithms to provide the data protection. A block of data is first encrypted using the AES-256 government encryption standard. The encrypted bits are then split into different shares and then each share is hashed using the National Security Agency's SHA-256 algorithm. One application of cryptographic splitting is to provide security for cloud computing. The encrypted data subsets can be stored on different clouds, with the information required to restore the data being held on a private cloud for additional security. Security vendor Security First Corp uses this technology for its Secure Parser Extended (SPx) product line. In 2009, technology services company Unisys gave a presentation about using cryptographic splitting with storage area networks. By splitting the data into different parts of the storage area network, this technique provided data redundancy in addition to security. Computer giant IBM has written about using the technology as part of its Cloud Data Encryption Services (ICDES). The technology has also been written about in the context of more effectively using sensitive corporate information, by entrusting different individuals within a company (trustees) with different parts of the information.

Machine Learning & Artificial Intelligence: Crash Course Computer Science #34
 
11:51
So we've talked a lot in this series about how computers fetch and display data, but how do they make decisions on this data? From spam filters and self-driving cars, to cutting edge medical diagnosis and real-time language translation, there has been an increasing need for our computers to learn from data and apply that knowledge to make predictions and decisions. This is the heart of machine learning which sits inside the more ambitious goal of artificial intelligence. We may be a long way from self-aware computers that think just like us, but with advancements in deep learning and artificial neural networks our computers are becoming more powerful than ever.

Now, I know this whole time, you've been hearing me say the word cipher, and been wondering, "What is a cipher, what is he talking about?" I'm going to explain it to you right now! A cipher is basically a circle, where all the B-Boys are in, alright? This is where we all dance. We create a circle, and one by one, we take turns dancing within the cipher. The cipher is where we get down, basically. I mean, that's the key word, cipher is like "Yo, let's go cipher." So we can say "Let's go cipher," meaning, "Let's go into the circle and do our thing." With one word, we just said that. "Let's go cipher." You know, that's what we do. That's what we call a cipher. So, a cipher is where everybody, not just our crew. I mean, you could have your own cipher within your crew, but you can't have a cipher with just two people, because that's not a circle. You need at least five people, or maybe four. You could probably do it with four. But, yeah. So cipher is where we get down, get busy, and, you know, we exchange how we feel according to the music at that moment and given time.

What is Manipulation? | Manipulation Techniques

What is manipulation? Manipulation is a serious psychological tool used by people to get other people to do what they want. This video shares 10 common signs of manipulative behavior. Subscribe to All Our Questions: https://youtube.com/c/allourquestions?sub_confirmation=1 Share this video: https://youtu.be/ig49aXCsioo At some point we have all seen signs of manipulation. Be it through a controlling boyfriend or girlfriend, a friend trying to get us to do what they want or even a child trying to convince you to get them another toy. Manipulative personalities can be very difficult to deal with but if you know the signs of manipulation then you can see the situation from a totally different perspective when someone is trying to pull an emotional or psychological manipulation trick on you. Here is the list I cover of ways people manipulate you: 1. They might ask you a ton of questions to figure out your strengths and weaknesses. 2. A manipulative person may distort facts if they don't align with their goal. 3. A manipulator could try to overwhelm you with information to leave you confused or defeated. 4. They could use aggressive behavior to intimidate you. 5. They could use negative language in the form of humor or sarcasm for psychological superiority. 6. A manipulative person may often judge,criticize or passively intimidate you. 7. They might try to make you feel guilty. 8. They may attempt to alienate you so they are your source of everything. 9. They might use your words against you to reposition themselves as the victim. 10. A person with manipulative behavior may discredit or diminish your problems to amplify their own. Of course there are a lot more ways people manipulate each other so if you want me to do another video with more ways just let me know in the comments.
