Blockchain tutorial 11: Elliptic Curve key pair generation
 
18:58
This is part 11 of the Blockchain tutorial explaining how the generate a public private key using Elliptic Curve. 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.

Bitcoin 101   Elliptic Curve Cryptography   Part 5   The Magic of Signing & Verifying
 
19:33
Vídeo original: https://youtu.be/U2bw_N6kQL8 There is nothing more magical in Bitcoin, or all of cryptography than digital signatures. And the most magical step of all is the verification. This is the step we focus on in this video, generating the entire process in just 50 lines of code (no imports or special function calls!) and watching as the Private Key falls out of the math entirely! So beautiful. The receiver is left with proof of the sender, confirmation of the message and no way of retrieving the senders private key. This is magic indeed.

Introduction to Encryption and Decryption
 
05:23
Data Encryption and Decryption. Encryption is the process of translating plain text data (plaintext) into something that appears to be random and meaningless (ciphertext). Decryption is the process of converting ciphertext back to plaintext. To encrypt more than a small amount of data, symmetric encryption is used.

Blockchain/Bitcoin for beginners 3: public/private keys, signatures... and first ever transaction
 
36:25
Detailed overview of public/private key encryption and live demo of exactly how digital signatures work on Mac, combining public and private keys and hash functions. Welcome to episode 3 of my series on Blockchain/Bitcoin. I'm joined once again by my girlfriend Nadisha who is my classroom pupil... I build on the hash function concepts from the previous episode and explain the basic concepts public and private keys and how to use them to create digital signatures - a key part of the bitcoin infrastructure. We demonstrate in a Mac terminal how you can generate your own keys and encrypt and decrypt and sign your own resources - learning by doing always works. We touch on bitcoin addresses, what they represent and how they are created. Finally I go back for a refresh of the bitcoin blockchain browser and look at the first ever bitcoin transaction in the "Genesis Block" to show what a real bitcoin address looks like.

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.

Cryptography/SSL 101 #2: Cryptographic hash functions
 
28:25
This video builds on the first one and introduces hash functions as a way to create a "unique" finger print of any digital entity like a number, a word or a file - anything that can be represented as a number.

Blockchain tutorial 15: Convert public, private key pairs to addresses
 
01:42
This is part 15 of the Blockchain tutorial explaining why some Blockchain implementations convert public, private key pairs to addresses. 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.

Blockchain/Bitcoin for beginners 8: Bitcoin addresses, public key hash, P2PKH transactions
 
23:28
Before we delve into the inner workings of a bitcoin transaction I wanted to explain how the actual bitcoin address is derived from the public key which in turn is derived from the private key. I take through step by step all the steps required to derived the checksums etc and show with a real example of a real bitcoin transaction. Also discuss why checksums are included in Bitcoin addresses in order to eliminate the possibility of characters being corrupted, or modified in transit. This is the cool tool for converted from base 58 encoded value to hex value. http://lenschulwitz.com/base58 Good link talking about base 58 encoding. https://en.bitcoin.it/wiki/Base58Check_encoding

RuhrSec 2017: "How to Build Hardware Trojans", Prof. Dr. Christof Paar
 
44:45
Countless systems ranging from consumer electronics to military equipment are dependent on integrated circuits (ICs). A surprisingly large number of embedded systems are already security-critical, e.g., medical devices, automotive electronics, SCADA systems or network routers. If the underlying ICs in an applications are maliciously manipulated through hardware Trojans, the security of the entire system can be compromised. In recent years, hardware Trojans have drawn the attention of governments and the scientific community. Even though hardware Trojans have been studied over the last 10 years or so, little is known about how they might look, especially those that are particularly designed to avoid detection. In this talk we introduce several approaches with which a sophisticated attacker could insert Trojan into hardware platforms. We will look at hardware Trojans realized on both, ASICs (application specific integrated circuits) and FPGAs, i.e., programmable hardware.
