Communicating "in the clear", Alice and Bob select two numbers, q and n. Alice then selects the secret number xa. Bob selects the secret number xb. From the two public numbers, q and n, and her secret ...

An encryption algorithm that was supposed to stand up to attacks from the future's most powerful computers was recently laid low by a much simpler machine. Reading time 2 minutes It turns out that ...

Whitfield Diffie and Martin Hellman's privacy-protecting technology has become both an inextricable part of modern life and a scourge to law enforcement. Stephen Shankland worked at CNET from 1998 to ...

Whitfield Diffie and Martin Hellman, whose names have been linked since their seminal paper introduced the concepts of public key encryption and digital signatures some 40 years ago, have been named ...

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 ...

There have been several rumors in the past detailing how the National Security Agency (NSA) can decrypt a substantial portion of encoded Internet traffic. This should not come as a surprise to some ...

In the 1970s, Whitfield Diffie co-wrote the recipe for one of today’s most widely used security algorithms in a paper called “New Directions in Cryptography.” The paper was a blueprint of what came to ...
