Scientists at Northwestern University say they have harnessed the properties of light to encrypt information into code that can be cracked only one way: by breaking the physical laws of nature. This ...

An American physicist and Canadian computer scientist received the A.M. Turing Award on Wednesday for their groundbreaking ...

Charles Bennett and Gilles Brassard were recognized for their foundational work in quantum information science.

Charles H Bennett and Gilles Brassard were recognised for introducing quantum mechanics to process and transmit information ...

I have a long and tattered history with cryptography. Ever since I learned about Bob and Alice I was smitten. I knew it was important because cryptographic algorithms could be used to protect ...

A private key, also known as a secret key, is a cryptographic key that is used to decrypt or digitally sign data. It is a crucial component in asymmetric encryption algorithms like RSA and ECC ...

Hardware faults are leaking hundreds of supposedly unbreakable encryption keys on to the internet, researchers have found – and spy agencies may be exploiting the loophole to read secret messages. RSA ...

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 ...
