Quantum Cryptography Explained in Under 6 Minutes
 
05:58
Quantum Cryptography explained simply. Regular encryption is breakable, but not quantum cryptography. Today we'll look at the simplest case of quantum cryptography, quantum key distribution. It uses the Heisenberg Uncertainty Principle to prevent eavesdroppers from cracking the code. Hi! I'm Jade.

Quantum Key Distribution and the Future of Encryption
 
27:06
By Konstantinos Karagiannis Quantum computing will bring tumultuous change to the world of information security in the coming decade. As multi-qubit systems use quantum algorithms to slice through even 4096-bit PK encryption in seconds, new Quantum Encryption will be required to ensure data security. Join Konstantinos for a look at real world experiments in Quantum Key Distribution that BT and partners have recently performed that show what the future of encryption will look like. Remember the panic after Heartbleed when SOME passwords needed to be changed? Imagine a day when ALL communications are at risk of eavesdropping via Quantum Computers - a day when only new systems that exploit the weirdness of quantum mechanics can ensure privacy.

Jintai Ding - ZHFE, a New Multivariate Public Key Encryption Scheme
 
22:32
Jintai Ding of the University of Cincinnati and the Chinese Academy of Sciences presented a talk titled: ZHFE, a new multivariate public key encryption scheme at the 2014 PQCrypto conference in October, 2014. Abstract: In this paper we propose a new multivariate public key encryption scheme named ZHFE. The public key is constructed using as core map two high rank HFE polynomials. The inversion of the public key is performed using a low degree polynomial of Hamming weight three. This low degree polynomial is obtained from the two high rank HFE polynomials, by means of a special reduction method that uses HFE polynomials. We show that ZHFE is relatively efficient and the it is secure against the main attacks that have threatened the security of HFE. We also propose parameters for a practical implementation of ZHFE.

The BB84 Protocol
 
08:06
A short video attempting to explain the Bennett & Brassard quantum cryptography protocol. I've omitted any mention of the particular details of quantum physics that would be involved in actual real-world implementations, such as particle polarization axes, spin, and so forth, instead replacing them with abstract "processes" and freakish mysterious "machines". The physical details (interesting though they are) are not needed to understand the basics of the protocol, and I'm no physicist, so I'd probably mess them up if I tried (assuming I haven't already!). Making these images has increased my affection for Microsoft PowerPoint, and putting them all into a video has hugely exacerbated my hatred for Windows Movie Maker. NOTE: An important missing piece of information: When Alice sends qubits to Bob, she chooses between process A and process B randomly for each qubit. NOTE 2: The following video explains BB84 as well, and gives more detail regarding the physics details: http://www.youtube.com/watch?v=7SMcf1MdOaQ NOTE 3: Here is another very interesting video about quantum cryptography. Any given real-world implementation, despite using the BB84 protocol, is bound to expose weaknesses that can be exploited. For example: http://www.youtube.com/watch?v=T0WnUlF2eAo

Quantum cryptography, animated
 
01:58
This animation by the Centre for Quantum Technologies at the National University of Singapore illustrates the process of quantum key distribution using entangled photons. The goal is for two people in different places to end up with identical keys by measuring these photons. We want these people - usually given the names Alice and Bob - to have a random sequence of 1s and 0s that they can use to scramble (and then unscramble) a message. The presence of entanglement between the photons means that any snooping will be revealed. Note: this animation has no sound.

Introduction to Quantum Cryptography and the Tokyo QKD Network
 
09:00
Quantum cryptography、consisting of quantum key distribution (QKD) and one-time pad encryption, allows for communication with unconditional security. In QKD systems, the senders encode information on single photons one by one, while the receivers measure the photon states and decode the information. By distilling possible eavesdropped bits, secure keys can be shared between the senders and receivers. Tokyo QKD Network, into which various quantum key distribution systems were integrated through cross platform, established upon NICT's test bed ("JGN2plus"). We have succeeded in the key-relay and the rerouting experiment using Tokyo QKD Network.

Quantum Cryptography in a Broader Context" as part of the Quantum Frontiers Distinguished Lecture Series on June 21, 2012. This talk is presented by the Institute for Quantum Computing and the University of Waterloo's Department of Physics and Astronomy. Abstract: It's often useful to have a private conversation within a public world. What role can quantum cryptography play in keeping conversations private? Sometimes described as providing "unconditional security guaranteed by the laws of quantum physics," its security implications are both tantalizing and surprisingly elusive. This talk introduces quantum cryptography and describes the speaker's experience creating several types of quantum cryptography equipment, within the broader context of mainstream cryptography and secure communications. Biography: Chip Elliott is Project Director for GENI, a suite of experimental infrastructure being created by the National Science Foundation for research in network science and engineering. He is a Fellow of the AAAS and IEEE, and an active inventor with over 80 issued patents.

What is QUANTUM CRYPTOGRAPHY? What does QUANTUM CRYPTOGRAPHY mean? QUANTUM CRYPTOGRAPHY meaning - QUANTUM CRYPTOGRAPHY definition - QUANTUM CRYPTOGRAPHY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem. Currently used popular public-key encryption and signature schemes (e.g., RSA and ElGamal) can be broken by quantum adversaries. The advantage of quantum cryptography lies in the fact that it allows the completion of various cryptographic tasks that are proven or conjectured to be impossible using only classical (i.e. non-quantum) communication (see below for examples). For example, it is impossible to copy data encoded in a quantum state and the very act of reading data encoded in a quantum state changes the state. This is used to detect eavesdropping in quantum key distribution. History: Quantum cryptography uses Heisenberg's uncertainty principle formulated in 1927, and the No-cloning theorem first articulated by Wootters and Zurek and Dieks in 1982. Werner Heisenberg discovered one of the fundamental principles of quantum mechanics: "At the instant at which the position of the electron is known, its momentum therefore can be known only up to magnitudes which correspond to that discontinuous change; thus, the more precisely the position is determined, the less precisely the momentum is known, and conversely” (Heisenberg, 1927: 174–5). This simply means that observation of quanta changes its behavior. By measuring the velocity of quanta we would affect it, and thereby change its position; if we want to find a quant's position, we are forced to change its velocity. Therefore, we cannot measure a quantum system's characteristics without changing it (Clark, n.d.) and we cannot record all characteristics of a quantum system before those characteristics are measured. The No-cloning theorem demonstrates that it is impossible to create a copy of an arbitrary unknown quantum state. This makes unobserved eavesdropping impossible because it will be quickly detected, thus greatly improving assurance that the communicated data remains private. Quantum cryptography was proposed first by Stephen Wiesner, then at Columbia University in New York, who, in the early 1970s, introduced the concept of quantum conjugate coding. His seminal paper titled "Conjugate Coding" was rejected by IEEE Information Theory Society, but was eventually published in 1983 in SIGACT News (15:1 pp. 78–88, 1983). In this paper he showed how to store or transmit two messages by encoding them in two "conjugate observables", such as linear and circular polarization of light, so that either, but not both, of which may be received and decoded. He illustrated his idea with a design of unforgeable bank notes. In 1984, building upon this work, Charles H. Bennett, of the IBM's Thomas J. Watson Research Center, and Gilles Brassard, of the Université de Montréal, proposed a method for secure communication based on Wiesner's "conjugate observables", which is now called BB84. In 1991 Artur Ekert developed a different approach to quantum key distribution based on peculiar quantum correlations known as quantum entanglement. Random rotations of the polarization by both parties (usually called Alice and Bob) have been proposed in Kak's three-stage quantum cryptography protocol. In principle, this method can be used for continuous, unbreakable encryption of data if single photons are used. The basic polarization rotation scheme has been implemented. The BB84 method is at the basis of quantum key distribution methods. Companies that manufacture quantum cryptography systems include MagiQ Technologies, Inc. (Boston, Massachusetts, United States), ID Quantique (Geneva, Switzerland), QuintessenceLabs (Canberra, Australia) and SeQureNet (Paris, France).

Quantum Cryptography Lecture
 
01:03:42
Quantum laser pointers brings you the infamous double slit experiment right in the palm of your hand. In 1801 English physicist Thomas Young performed this experiment to determine if light was a particle or a wave. A laser shines a coherent beam of light through a film disc containing two parallel slits. Light striking the wall behind the slits producers a classic interference pattern. This surprising result means light passes through the parallel slits not as particles but as waves. When the peaks of two waves overlap it creates a band of light. When the peak of one wave meets the valley of another, light is cancelled out. Variations of this experiment spurred public debates between Albert Einstein and Neils Bohr on the true nature of reality. It’s been called the granddaddy of all quantum weirdness. This convenient and affordable double slit laser was designed for personal enjoyment and education.

Cryptography basics: What is Encryption and Decryption
 
06:45
Get Full Course: http://www.engineeringmentor.com/CNYTv3 Networks #3: This tutorial introduces the Cryptography basics. It also explains what is Encryption and Decryption. a) Cryptography basics (00:21):http://youtu.be/BEb_AnPWPwY?t=21s how do we provide this security during transmission? Well, One way of ensuring security can be use of CRYPTOGRAPHY! Cryptography is a field of network security which deals with hiding "real" infromation when it is under transmission between the two parties. Usually, the real information is transformed or hidden into another message and transmitted over the network. This transformed message in itself will make no sense even if any hacker gets hold of this information. When it reaches the destination, the receipent will know a method to de-transform the garbage message into the original information which the sender had sent.method of transforming message at sender's side and de transforming at reciever's side forms the basic model of Cryptography. b) Encryption and Decryption (3:57):http://youtu.be/BEb_AnPWPwY?t=3m57s First, the information to be transmitted, called as plain text(or message) is fed to an Encryption system. The Encyrption system uses a key to convert the plain text to encyrpted form which looks like garbage value. This is also called as cipher text. A corresponding key is used at the other end to decrypt the cipher text back to original message. When we say a key, it actually means a piece of string value which is fed to encyprtion and decryption algorithms along with the text for transformation. When the message reaches the destination, this system at the other end decrypts the cipher text into original message with the help of the key. This is called as Decryption System. The output of the Decryption System is the intended message. Depending on how the keys are shared, we can classify crytography as symmetric and asymmetric. If the keys used by both parties are same, then it is called symmetric key cryptography, or private key cryptography. If both parties use different keys for encyrption and decryption, then it is called asymmetric key cryptography or public key cryptography. video URL : https://www.youtube.com/watch?v=BEb_AnPWPwY Watch ALL CN VIDEOS: https://www.youtube.com/playlist?list=PL9OIoIp8YySF4mkIihOb_j2HZIRIlYuEx For more, visit http://www.EngineeringMentor.com Facebook: https://www.facebook.com/EngineeringMentor Twitter : https://twitter.com/Engi_Mentor

Code for 'Unbreakable' Quantum Encryption

The NIST quantum key distribution (QKD) system uses single photons, the smallest particles of light, in different orientations to produce a continuous binary code, or "key," for encrypting information. The rules of quantum mechanics ensure that anyone intercepting the key is detected, thus providing highly secure key exchange. The laboratory system produced this "raw" key at a rate of more than 4 million bits per second (4 million bps) over 1 kilometer (km) of optical fiber, twice the speed of NIST's previous record, reported just last month.** The system also worked successfully, although more slowly, over 4 km of fiber. more info http://www.nist.gov/public_affairs/releases/quantumfiber.htm captioned video avaliable

Chris Peikert - Lattice Cryptography for the Internet
 
24:58
Chris Peikert of Georgia Institute of Technology presented a talk titled: Lattice cryptography for the internet at the 2014 PQCrypto conference in October, 2014. Abstract: In recent years, lattice-based cryptography has been recognized for its many attractive properties, such as strong provable security guarantees and apparent resistance to quantum attacks, flexibility for realizing powerful tools like fully homomorphic encryption, and high asymptotic efficiency. Indeed, several works have demonstrated that for basic tasks like encryption and authentication, lattice-based primitives can have performance competitive with (or even surpassing) those based on classical mechanisms like RSA or Diffie-Hellman. However, there still has been relatively little work on developing lattice cryptography for deployment in real-world cryptosystems and protocols. In this work, we take a step toward that goal, by giving efficient and practical lattice-based protocols for key transport, encryption, and authenticated key exchange that are suitable as "drop-in" components for proposed Internet standards and other open protocols. The security of all our proposals is provable based (sometimes in the random-oracle model) on the well-studied "leaning with errors over rings" problem, and hence on the conjectured worst-case hardness of problems on ideal lattices (against quantum algorithms). One of our main technical innovations (which may be of independent interest) is a simple, low-bandwidth reconciliation technique that allows two parties who "approximately agree" on a secret value to reach exact agreement, a setting common to essentially all lattice-bases encryption schemes. Our technique reduces the ciphertext length of prior (already compact) encryption schemes nearly twofold, at essentially no cost.

26C3: How you can build an eavesdropper for a quantum cryptosystem 1/6
 
10:00
Clip 1/6 Speakers: Qin Liu ,Sebastien Sauge This presentation will show the first experimental implementation of an eavesdropper for quantum cryptosystem. Although quantum cryptography has been proven unconditionally secure, by exploiting physical imperfections (detector vulnerability) we have successfully built an intercept-resend attack and demonstrated eavesdropping under realistic conditions on an installed quantum key distribution line. The actual eavesdropping hardware we have built will be shown during the conference. For more information go to: http://events.ccc.de/congress/2009/Fahrplan/events/3576.en.html
