In my previous article/video how does encryption work? I wrote about the principles of encryption starting with the Caesar cipher and following the development of cryptography through to the modern ...

The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works. Whitfield Diffie and Martin ...

We all know the usual jokes about the ‘S’ in ‘IoT’ standing for ‘Security’. It’s hardly a secret that security in embedded, networked devices (‘IoT devices’) is all too often a last-minute task that ...

On Tuesday, the Association for Computing Machinery, the nation’s leading organization for computer science, awarded its annual top prize of $1 million to two men whose name will forever be ...

Attackers are recording, and sometimes forging, vast volumes of human communication. Some of this communication is protected by cryptographic systems such as the Rivest–Shamir–Adleman (RSA) system and ...

Encryption is one of the pillars of modern-day communications. You have devices that use encryption all the time, even if you are not aware of it. There are so many applications and systems using it ...

Understand the crypto concepts behind the modern internet security infrastructure, from digital signatures and transport layer security to blockchains and Bitcoin. Cryptography grows ever more ...
