Elliptic Curve ElGamal Cryptosystem
 
03:48
In this video I primarily do through the Elliptic Curve ElGamal crytposystem (Bob's variables/computations, Alice's variables/computations, what is sent, and how it is decrypted by Bob). In addition, I go over the basics of elliptic curves such as their advantages and how they are written.

Blockchain tutorial 9: Discrete logarithm
 
06:26
This is part 9 of the Blockchain tutorial explaining what discrete logarithms are. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

Streamed live on Jul 29, 2012 Episode #14 of The Social Sports and Entertainment Show with Chris Yates features special guest Amin El Gamal who is an actor who was the guest star on "The Newsroom" episode 5. Amin joined us with a friend of his from college, Jill Wurzburg, and his brother, Abrahim El Gamal. Amin really opened up and talked about how attending "clown school" during college made him prepared for anything. His brother was a big help in bringing up how Amin was involved in theater even when he was six when he started a production company out of his garage with stuffed animals as the cast. He even shared information about how his grandmother was a child actress and how she influenced him to become an actor. During Amin's time on "The Newsroom" set he was able to meet some of the cast/crew and shared a few of his thoughts about them during the broadcast. He speaks about the large differences between the film industry and the way a theater is ran. Amin even explains what he did to prepare for the show and how the research that he did helped him with influencing the crew on making some subtle changes to the show that made a large difference.

In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption.

We designed ECDSA with the purpose to improve performance and security respectively by using elliptic curve point multiplication on Koblitz curves to compute the public key and a key stream generator “W7” to generate private key. Different blocs of ECDSA are implemented on a reconfigurable hardware platform (Xilinx xc6vlx760-2ff1760). We used the hardware description language VHDL (VHSIC Hardware Description Language) for compartmental validation. The design requires 0.2 ms, 0.8 ms and 0.4 ms with 7 %, 13 % and 5 % of the device resources on Slice LUT for respectively key generation, signature generation and signature verification. The proposed ECDSA implementation is suitable to the applications that need: low-bandwidth communication, low-storage and low-computation environments. In particular our implementation is suitable to smart cards and wireless devices.

Affine Cipher - Decryption (Known Plaintext Attack)
 
07:04
In this video I talk about ways to decrypt the Affine Cipher when the key is NOT known. Specifically, I go over an example of the known plaintext attack. 3^(-1) = 9 (mod 26) math worked out (Euclidean Algorithm): 1. Forwards: 26 = 3(8) + 2 3 = 2(1) + 1 2. Backwords: 1 = 3 - 2(1) 1 = 3(1) - (26 - 3(8))(1) 1 = 3(1) - 26 + 3(8) 1 + 26 = 3(9) 1 (mod 26) = 3(9) Hence 9 is the inverse.
