IBM adds NIST’s new public-key encryption and digital signatures algorithms to defend against attacks by future quantum computers. While the need for it may be years away, IBM has added additional ...

The original version of this story appeared in Quanta Magazine. For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a ...

When I began programming microcontrollers in 2003, I had picked up the Atmel STK-500 and learned assembler for their ATtiny and ATmega lines. At the time I thought it was great – the emulator and ...

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 ...

Public-key encryption, as noted in the profile of cryptographer Bruce Schneier, is complicated in detail but simple in outline. The article below is an outline of the principles of the most common ...

We don’t know when, but it will happen: Quantum computers will become so powerful that all existing public-key cryptography protections will be quickly crackable. According to Dr. Mark Jackson of ...

Wong: So, Joppe, could you tell us why we need a new standard for public-key encryption? Bos: Yeah, thanks. Publicly, encryption is one of the key components in cryptography, so I'll use symmetric key ...

In the context of cryptography, a public key is an alphanumeric string that serves as an essential component of asymmetric encryption algorithms. It is typically derived from a private key, which must ...
