Adi Shamir: "We are losing the cibersecurity war"
 
02:39
The BBVA Foundation Frontiers of Knowledge Award in the Information and Communication Technologies category goes, in this tenth edition, to Shafi Goldwasser, Silvio Micali, Ronald Rivest and Adi Shamir for their “fundamental contributions to modern cryptology, an area of a tremendous impact on our everyday life,” in the words of the jury’s citation. “Their advanced crypto-protocols enable the safe and secure transmission of electronic data, ranging from e-mail to financial transactions. In addition, their work provides the underpinning for digital signatures, blockchains and crypto-currencies,” like Bitcoin.

Algorand - A Truly Decentralised Consensus Mechanism
 
06:59
Algorand is a new consensus mechanism that scales faster and is more decentralised than proof-of-work or proof-of-stake. Invented by MIT professor Silvio Micali, Algorand is poised to be one of the largest and most ambitious projects of 2018. Erick Blockchain of the Blockchain Brief breaks down how Algorand's Byzantine Agreement consensus mechanism stands apart and why it's big news for blockchain. twitter.com/BriefBlockchain steemit.com/BlockchainBrief

Secret sharing

If you find our videos helpful you can support us by buying something from amazon. https://www.amazon.com/?tag=wiki-audio-20 Secret sharing Secret sharing (also called secret splitting) refers to methods for distributing a secret amongst a group of participants, each of whom is allocated a share of the secret.The secret can be reconstructed only when a sufficient number, of possibly different types, of shares are combined together; individual shares are of no use on their own. =======Image-Copyright-Info======== License: Creative Commons Attribution-Share Alike 4.0 (CC BY-SA 4.0) LicenseLink: http://creativecommons.org/licenses/by-sa/4.0 Author-Info: Fred the Oyster Image Source: https://en.wikipedia.org/wiki/File:Secretsharing_3-point.svg =======Image-Copyright-Info======== -Video is targeted to blind users Attribution: Article text available under CC-BY-SA image source in video https://www.youtube.com/watch?v=4b8tlv56E9w

History of Bitcoin
 
26:38
Bitcoin is a cryptocurrency, a form of money that uses cryptography to control its creation and management, rather than relying on central authorities. However, not all of the technologies and concepts that make up bitcoin are new; the presumed pseudonymous Satoshi Nakamoto integrated many existing ideas from the cypherpunk community when creating bitcoin.

Cryptography
 
46:35
Cryptography is the practice and study of techniques for secure communication in the presence of third parties . More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation. Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce. This video targeted to blind users.

Public-key cryptography
 
44:57
Public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic algorithms which require two separate keys, one of which is secret (or private) and one of which is public. Although different, the two parts of this key pair are mathematically linked. The public key is used to encrypt plaintext or to verify a digital signature; whereas the private key is used to decrypt ciphertext or to create a digital signature. The term "asymmetric" stems from the use of different keys to perform these opposite functions, each the inverse of the other -- as contrasted with conventional ("symmetric") cryptography which relies on the same key to perform both. Public-key algorithms are based on mathematical problems which currently admit no efficient solution that are inherent in certain integer factorization, discrete logarithm, and elliptic curve relationships. It is computationally easy for a user to generate their own public and private key-pair and to use them for encryption and decryption. The strength lies in the fact that it is "impossible" (computationally infeasible) for a properly generated private key to be determined from its corresponding public key. Thus the public key may be published without compromising security, whereas the private key must not be revealed to anyone not authorized to read messages or perform digital signatures. Public key algorithms, unlike symmetric key algorithms, do not require a secure initial exchange of one (or more) secret keys between the parties. This video is targeted to blind users.

Digital signature
 
26:54
A digital signature is a mathematical scheme for demonstrating the authenticity of a digital message or document. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, such that the sender cannot deny having sent the message (authentication and non-repudiation) and that the message was not altered in transit (integrity). Digital signatures are commonly used for software distribution, financial transactions, and in other cases where it is important to detect forgery or tampering. This video is targeted to blind users.
