As a Bitcoiner, you’re going to need a secure way to communicate privately, without relying on a company to encrypt your data for you. For example, freely available methods with end-to-end encryption ...

The protocol removes reliance on pre-shared keys and central authorities, making it suitable for scalable smart city ...

Public-key cryptography (PKC, or asymmetric cryptography) had a revolutionary effect on the theory of cryptography. PKC’s use of pure mathematical hard problems led to a study of academic, theoretical ...

The security system that underlies the internet makes use of a curious fact: You can broadcast part of your encryption to make your information much more secure. When you purchase through links on our ...

Public key encryption has long been a cornerstone in securing digital communications, allowing messages to be encrypted with a recipient’s publicly available key while only being decrypted by the ...

I’m going to talk about the security behind Bitcoin addresses and keys, called Public Key Cryptography. This includes SHA256, Random Number Generators(RNGs), Hash Functions, and Elliptic Curve Digital ...

Just weeks after US president Joe Biden signed into law the Quantum Computing Cybersecurity Preparedness Act, there are reports that Chinese researchers have cracked RSA 2048 bit encryption. Given ...

This course covers the basic knowledge in understanding and using cryptography. The main focus is on definitions, theoretical foundations, and rigorous proofs of security, with some programming ...

The famous cryptographers Leonard Adleman, Ronald Rivest, and Adi Shamir – the developers of the RSA encryption code – received the Association for Computing Machinery’s 2002 Turing Award “for their ...
