Kerberos - authentication protocol
 
06:08
At 4:30: A mistake: step 3: When the file server gets the token, it "decrypts" (not "encrypts") the token with the secret key shared with TGS. In Greek mythology, Kerberos is a dog with three heads. But today I will not talk about the dog. Kerberos is an authentication protocol for client/server applications. I will demonstrate with an example how Kerberos works. Keep in mind, Kerberos implements private key encryption.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, deniable authentication refers to message authentication between a set of participants where the participants themselves can be confident in the authenticity of the messages, but it cannot be proved to a third party after the event. In practice, deniable authentication between two parties can be achieved through the use of message authentication codes (MACs) by making sure that if an attacker is able to decrypt the messages, they would also know the MAC key as part of the protocol, and would thus be able to forge authentic-looking messages. For example, in the Off-the-Record Messaging (OTR) protocol, MAC keys are derived from the asymmetric decryption key through a cryptographic hash function. In addition to that, the OTR protocol also reveals used MAC keys as part of the next message, when they have already been used to previously received messages and will not be re-used.

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 CRYPTOGRAPHIC NONCE? What does CRYPTOGRAPHIC NONCE mean? CRYPTOGRAPHIC NONCE meaning

What is CRYPTOGRAPHIC NONCE? What does CRYPTOGRAPHIC NONCE mean? CRYPTOGRAPHIC NONCE meaning - CRYPTOGRAPHIC NONCE definition - CRYPTOGRAPHIC NONCE 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 In cryptography, a nonce is an arbitrary number that may only be used once. It is similar in spirit to a nonce word, hence the name. It is often a random or pseudo-random number issued in an authentication protocol to ensure that old communications cannot be reused in replay attacks. They can also be useful as initialization vectors and in cryptographic hash function. A nonce is an arbitrary number used only once in a cryptographic communication, in the spirit of a nonce word. They are often random or pseudo-random numbers. Many nonces also include a timestamp to ensure exact timeliness, though this requires clock synchronization between organizations. The addition of a client nonce ("cnonce") helps to improve the security in some ways as implemented in digest access authentication. To ensure that a nonce is used only once, it should be time-variant (including a suitably fine-grained timestamp in its value), or generated with enough random bits to ensure a probabilistically insignificant chance of repeating a previously generated value. Some authors define pseudo-randomness (or unpredictability) as a requirement for a nonce. Authentication protocols may use nonces to ensure that old communications cannot be reused in replay attacks. For instance, nonces are used in HTTP digest access authentication to calculate an MD5 digest of the password. The nonces are different each time the 401 authentication challenge response code is presented, thus making replay attacks virtually impossible. The scenario of ordering products over the Internet can provide an example of the usefulness of nonces in replay attacks. An attacker could take the encrypted information and—without needing to decrypt—could continue to send a particular order to the supplier, thereby ordering products over and over again under the same name and purchase information. The nonce is used to give 'originality' to a given message so that if the company receives any other orders from the same person with the same nonce, it will discard those as invalid orders. A nonce may be used to ensure security for a stream cipher. Where the same key is used for more than one message and then a different nonce is used to ensure that the keystream is different for different messages encrypted with that key; often the message number is used. Secret nonce values are used by the Lamport signature scheme as a signer-side secret which can be selectively revealed for comparison to public hashes for signature creation and verification. Initialization vectors may be referred to as nonces, as they are typically random or pseudo-random. Nonces are used in proof-of-work systems to vary the input to a cryptographic hash function so as to obtain a hash for a certain input that fulfills certain arbitrary conditions. In doing so, it becomes far more difficult to create a "desirable" hash than to verify it, shifting the burden of work onto one side of a transaction or system. For example, proof of work, using hash functions, was considered as a means to combat email spam by forcing email senders to find a hash value for the email (which included a timestamp to prevent pre-computation of useful hashes for later use) that had an arbitrary number of leading zeroes, by hashing the same input with a large number of nonce values until a "desirable" hash was obtained. Similarly, the bitcoin block-chain hashing algorithm can be tuned to an arbitrary difficulty by changing the required minimum/maximum value of the hash so that the number of bitcoins awarded for new blocks does not increase linearly with increased network computation power as new users join. This is likewise achieved by forcing bitcoin miners to add nonce values to the value being hashed to change the hash algorithm output. Because cryptographic hash algorithms cannot easily be predicted based on their inputs, this makes the act of blockchain hashing and the possibility of being awarded bitcoins something of a lottery, where the first "miner" to find a nonce that delivers a desirable hash is awarded valuable bitcoins.

Authentication And Ciphering (Security) In GSM Network
 
18:02
Presenter: Dr Moazzam Tiwana website: drmoazzam.com This lecture explains what are authentication and ciphering procedures in GSM (Global System For Mobiles). Important aspects of the security of GSM network. Authentication is meant to stop the illegal use of the network by unauthorized users. A3 algorithm is used for this purpose. It uses RAND and Ki as its input and generates SRES. Which is then compared with the SRES generated on the network side. If the two match, the authentication is successful. In the second step ciphering or encryption of data between BTS and MS (Mobile Station) starts. Ciphering key Kc is generated using A8 algorithm which uses Ki and RAND as its input. The ciphering key Kc and Frame number is then used by A5 algorithm to encrypt user data in the blocks of 114 bits each.

A cryptographic protocol is a protocol executed by several distant agents through a network where the messages or part of the messages are produced using cryptographic functions (encryption, hashing, etc.). Cryptographic protocols are used for various purpose between the agents:. May 7, 2006 - This is regarded as offensive because of the malicious payload normally embedded in the virus, and because of the use of anti-anti-virus techniques For instance, on networks some layer 2 protocols are based on crypto (WEP, WPA/TKIP, and others), as are some upper layer protocols (IPSec, SSH, SSL, primitives such as commutative encryption. We give a list of some relevant al- gebraic properties of cryptographic operators, and for each of them, we provide examples of protocols or attacks using these properties. We also give an overview of the existing methods in formal approaches for analyzing cryptographic proto-. Using cryptographic techniques, it may be possible to allow intermediate results in a distributed algorithm to be certified independently of who provides them, reducing themes of complexity theory, e.g., interactive provability, average vs. worst-case complexity, and the inherent communication costs of multiparty protocols. Web is an electronic protocol which allows people to communicate mail, information, and commerce through a digital medium. This new method of information exchange has caused a tremendous need for information security. A thorough understanding of cryptography and encryption will help people develop better ways to etc. The analysis techniques discussed in this survey assume per- fect cryptography. This means that cryptographic primitives are considered as black boxes satisfying certain properties, as described in section 2.1. below.

Secondly, the individual has to carry at least one human authentication factor that may be recognized on the distinct time and in a certain location. Thirdly, the distinct time must be equipped with a resident means that is capable to determine the appearance or passage or otherwise coincidence of individual at this distinct location. It makes no sense to define a starting time or a time span without constraints of location. No granting of access is known without defining a distinct location where this access shall be granted. Basic requirement for safe time based authentication is a well defined separation of locations as well as an equally well defined proximity of the applying individual to this location. Time-based authentication is a standard procedure to grant access to an area by detecting a person at an entrance an opening the barrier at a certain time. This of course does not limit the presence of the person in the entered area after once passing the barrier. Time-based authentication is a standard procedure to get access to a machine, especially a working position with a computer and the functions of this computer within a certain span of time. Such granted access may be automatically terminated.

17 - Jean Lancrenon - On Password-Authenticated Key Exchange Security Modeling
 
22:36
On Password-Authenticated Key Exchange Security Modeling Abstract: Deciding which security model is the right one for Authenticated Key Exchange (AKE) is well-known to be a difficult problem. In this paper, we examine definitions of security for Password-AKE (PAKE) in the style proposed by Bellare et al. at Eurocrypt 2000. Indeed, there does not seem to be any consensus, even when narrowing the study down to this particular authentication method and model style, on how to precisely define fundamental notions such as accepting, terminating, and partnering. The aim of this paper is to begin addressing this problem. We first show how definitions vary from paper to paper. We then propose and thoroughly motivate a definition of our own, and use the opportunity to correct a minor flaw in a more recent and more PAKE-appropriate model proposed by Abdalla et al. at Public Key Cryptography 2005. Finally, we argue that the uniqueness of partners holding with overwhelming probability ought to be an explicitly required and proven property for AKE in general, but even more so in the password case, where the optimal security bound one aims to achieve is no longer a negligible value. To drive this last point, we exhibit a protocol that is provably secure following the Abdalla et al. definition, and at the same time fails to satisfy this property. -- Jean Lancrenon has been a research associate at SnT since January 2012, in Prof. Peter YA Ryan’s group (ApSIA). He obtained his PhD from the Université Joseph Fourier (Grenoble, France) in June 2011. His research mainly focuses on the security modeling of cryptographic services with a particular emphasis on authenticated key exchange protocols.

What is CRYPTOCAT? What does CRYPTOCAT mean? CRYPTOCAT meaning, definition & explanation

What is CRYPTOCAT? What does CRYPTOCAT mean? CRYPTOCAT meaning - CRYPTOCAT pronunciation - CRYPTOCAT definition - CRYPTOCAT explanation - How to pronounce CRYPTOCAT? SUBSCRIBE to our Google Earth flights channel - http://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ?sub_confirmation=1 Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Cryptocat is an open source desktop application intended to allow encrypted online chatting available for Windows, OS X, and Linux. It uses end-to-end encryption to secure all communications to other Cryptocat users. Users are given the option of independently verifying their buddies' device lists and are notified when a buddy's device list is modified and all updates are verified through the built-in update downloader. Cryptocat is developed by Nadim Kobeissi and a community of open source contributors and is published under the terms of the GPLv3 license. Cryptocat was first launched on 19 May 2011 as a web application. In June 2012, Kobeissi said he was detained at the U.S. border by the DHS and questioned about Cryptocat's censorship resistance. He tweeted about the incident afterwards, resulting in media coverage and a spike in the popularity of the software. In June 2013, security researcher Steve Thomas pointed out a security bug that could be used to decrypt any group chat message that had taken place using Cryptocat between September 2012 and April 19, 2013. Private messages were not affected, and the bug had been resolved a month prior. In response, Cryptocat issued a security advisory, requested that all users ensure that they had upgraded, and informed users that past group conversations may have been compromised. In February 2014, an audit by iSec Partners criticized Cryptocat's authentication model as insufficient. In response, Cryptocat made improvements to user authentication, making it easier for users to authenticate and detect man-in-the-middle attacks. In February 2016, citing dissatisfaction with the project's current state after 19 months of non-maintenance, Kobeissi announced that he would be taking Cryptocat temporarily offline and discontinuing the development of its mobile application, pending a complete rewrite and relaunch of the software. In March 2016 Kobeissi announced the re-release of Cryptocat, rewritten completely as desktop software instead of the original web application software, as a public beta and the resumption of the service. The new desktop-centric approach allowed Cryptocat to benefit from stronger desktop integration, in a style similar to Pidgin. Cryptocat allows its users to set up end-to-end encrypted chat conversations. Users can exchange one-to-one messages, encrypted files, photos as well as create and share audio/video recordings. All devices linked to Cryptocat accounts will receive forward secure messages, even when offline. All messages, files and audio/video recordings sent over Cryptocat are end-to-end encrypted. Cryptocat users link their devices to their Cryptocat account upon connection, and can identify each other's devices via the client's device manager in order to prevent man-in-the-middle attacks. Cryptocat also employs a Trust on first use mechanism in order to help detect device identity key changes. Cryptocat also includes a built-in auto-update mechanism that automatically performs a signature check on downloaded updates in order to verify authenticity, and employs TLS certificate pinning in order to prevent network impersonation attacks. Originally in 2013, Cryptocat offered the ability to connect to Facebook Messenger to initiate encrypted chatting with other Cryptocat users. According to the developers, the feature was meant to help offer an alternative to the regular Cryptocat chat model which did not offer long-term contact lists. This feature was disconnected in November 2015. ....
