I introduce practical attacks on quantum cryptography, and give several examples of attacks and countermeasures. This is lecture 2 in the series, however if you are familiar with the basics of quantum cryptography (introduced in lecture 1 http://goo.gl/vue6U2), you can start with this lecture.

Introduction to Lattice Based Cryptography
 
07:08
This short video introduces the concept of a lattice, why they are being considered as the basis for the next generation of public key cryptography, and a short walkthrough of a specific encryption algorithm. For a very thorough paper designed to be readable for undergraduates I highly recommend https://eprint.iacr.org/2015/938.pdf. *One technical note: At 1:30 I claim that lattices are composed only of integers. This is not true. Some lattices only contain integers, but in general, any rational number will do.

Future ready – post-quantum encryption demonstrated on OnlyKey
 
00:10
Today we are demonstrating the first implementation of post-quantum crypto on the OnlyKey. This is the first step in making OnlyKey the first commercially available post-quantum encryption device. This proof-of-concept essentially demonstrates that post-quantum algorithms like NewHope Simple are OnlyKey compatible. While this is a long way from a user ready solution, we have been able to successfully integrate OnlyKey’s random number generator with the Newhope Simple implementation provided by Dr. Michael Scott. In this simple example two participants, Alice and Bob, who have no prior arrangement, establish a secret key on the OnlyKey. This is initiated by having the OnlyKey connected and loading a web application that tells OnlyKey to run the test.

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.

The Quantum Internet | Stephanie Wehner | TEDxVienna
 
15:05
The goal of a quantum internet is to connect quantum processors using long distance quantum communication. The internet has had a revolutionary impact on our world. The long-term vision of this talk is to build a matching quantum internet that will operate in parallel to the internet we have today. This quantum internet will enable long-range quantum communication in order to achieve unparalleled capabilities that are provably impossible using only classical means. Stephanie starts by exploring what a quantum internet is good for, and gives an intuition why quantum communication is so powerful. She proceeds from the state of the art today, towards stages for a full blown quantum internet. As an example, she discusses the efforts of the EU quantum internet alliance including the planned demonstration network connecting four Dutch cities in 2020. Stephanie Wehner is an Antoni van Leeuwenhoek Professor at QuTech, Delft University of Technology, where she leads the Quantum Internet efforts. Her passion is the theory of quantum information in all its facets, and she has written numerous scientific articles in both physics and computer science. In a former life, she worked as a professional hacker in industry. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Cryptography in the Open: History of Crypto and the NSA
 
39:16
Henry Corrigan-Gibbs reviews the history of Diffie-Hellman key exchange and how the NSA fought to keep the authors from publishing. He will give a bit of information that was not in his Stanford Magazine article on the topic. Henry is a Ph.D. student at Stanford working on cryptography under Dan Boneh. His research has included work on Riposte, an anonymous messaging system for millions of users.

Shor's Algorithm in Mathematica
 
07:51
This calculations are available at http://homepage.cem.itesm.mx/lgomez/quantum/v7phase.pdf Shor's Factoring Algorithm is very important because it showed that a Quantum Computer will be more efficient than a normal computer when solving some important, practical problems (Factorization is important in the secure transmision of electronic data, like credit card numbers). This video shows briefly how Shor's algorithm can be simulated in Mathematica using the free Quantum add-on. Quantum is available at http://homepage.cem.itesm.mx/lgomez/quantum/ Jose Mexico
