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.

Vídeo original: https://youtu.be/iB3HcPgm_FI Welcome to part four in our series on Elliptic Curve Cryptography. I this episode we dive into the development of the public key. In just 44 lines of code, with no special functions or imports, we produce the elliptic curve public key for use in Bitcoin. Better still, we walk you through it line by line, constant by constant. Nothing makes the process clearer and easier to understand than seeing it in straight forward code. If you've been wondering about the secp256k1 (arguably the most important piece of code in Bitcoin), well then this is the video for you. This is part 4 of our upcoming series on Elliptic Curves. Because of such strong requests, even though this is part 4, it is the first one we are releasing. In the next few weeks we will release the rest of the series. Enjoy.

Elliptic curves are relatively obscure mathematical objects: you can get a PhD in maths without ever having come across them. Yet these objects play an important role in modern cryptography and as such are found in most HTTPS connections, in Bitcoin, and in a large number of other places. To really understand elliptic curve cryptography (ECC) to the point that you can implement algorithms, you'd have to study the maths behind it. This talk assumes that you haven't studied the maths, but just want to understand what ECC is about, how is works and how it is implemented. It will discuss how 'point addition' works and how the Elliptic Curve Diffie-Hellman algorithm is used, for example in HTTPS - and how you can find it using Wireshark. It will explain how to use elliptic curve for digital signatures and why you don't want to be like Sony when it comes to implementing them. It will discuss how ECC was used in an infamous random number generator and, finally, will take a brief look at the use of elliptic curves in post-quantum algorithms. The goal of this talk is to keep things simple and understandable and no knowledge of maths is assumed. The talk won't make you an expert on ECC -- that would take years of studying. But it might help you understand the context a bit better when you come across them in your research. And hopefully it will also be a little bit fun. -- Martijn Grooten is a lapsed mathematician who by chance ended up working in security - and loved it. He's spend more than a decade testing security software but his interest in security is broad and he has a weak spot for cryptography. He currently is Editor of Virus Bulletin.

Elliptic Curve Cryptography (ECC) is hot. Far better scalable than traditional encryption, more and more data and networks are being protected using ECC. Not many people know the gory details of ECC though, which given its increasing prevalence is a very bad thing. In this presentation I will turn all members of the audience into ECC experts who will be able to implement the relevant algorithms and also audit existing implementations to find weaknesses or backdoors. Actually, I won't. To fully understand ECC to a point where you could use it in practice, you would need to spend years inside university lecture rooms to study number theory, geometry and software engineering. And then you can probably still be fooled by a backdoored implementation. What I will do, however, is explain the basics of ECC. I'll skip over the gory maths (it will help if you can add up, but that's about the extent of it) and explain how this funny thing referred to as "point addition on curves" can be used to exchange a secret code between two entities over a public connection. I will also explain how the infamous backdoor in Dual_EC_DRGB (a random number generator that uses the same kind of maths) worked. At the end of the presentation, you'll still not be able to find such backdoors yourselves and you probably realise you never will. But you will be able to understand articles about ECC a little better. And, hopefully, you will be convinced it is important that we educate more people to become ECC-experts.

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.

"Lenstra's elliptic curve factorization method," given by Leo Lai on 27th January 2016 as a guest speaker in the Churchill Computer Science Talks Series (http://talks.cam.ac.uk/show/index/63165). Leo's talk addresses something incredibly important to computer science: computational number theory. Computational number theory has deep links to cryptography and security, and one of the most fundamental problems is the factorization of huge numbers, the subject of this talk. Abstract: Integer factorization is an important problem in computational number theory with many applications in cryptography. Elliptic curves, on the other hands, are mathematical objects whose study predates the notion of computation by more than a century. In 1987, Lenstra described a new factoring algorithm using elliptic curves, which is still one of the fastest special purpose factorization algorithms invented so far. Conversely, the desire to rigorously analyze this algorithm has produced new results in number theory. This talk will describe his algorithm. No knowledge beyond basic number theory is required.

Cryptography generally relies heavily on modular arithmetic. Lisp’s ability to change the language syntax and define generic functions provides opportunities to implement modular arithmetic operations much more cleanly than other languages. Video notes The audio for the introduction and for the questions from the audience is hard to hear. I will try to improve on that in the next batch of talks. — Arthur

Much of the research in number theory, like mathematics as a whole, has been inspired by hard problems which are easy to state. A famous example is 'Fermat's Last Theorem'. Starting in the 1970's number theoretic problems have been suggested as the basis for cryptosystems, such as RSA and Diffie-Hellman. In 1985 Koblitz and Miller independently suggested that the discrete logarithm problem on elliptic curves might be more secure than the 'conventional' discrete logarithm on multiplicative groups of finite fields. Since then it has inspired a great deal of research in number theory and geometry in an attempt to understand its security. I'll give a brief historical tour concerning the elliptic curve discrete logarithm problem, and the closely connected Weil Pairing algorithm.

This video demonstrate the process of image encryption using elliptical curve cryptography. The complete code for it is available at https://free-thesis.com/product/image-encryption-decryption-using-ecc/. This is the code which simulates the encryption and decryption of an image using random and private keys in MATLAB. The elliptic curve cryptography is applied to achieve the security of any image before transmitting it to some one so that no other can see the data hidden in the image. At the receiver end the destined user will already have the decryption key used for this. If key is altered, image will not be decrypted.
