One of the potential encryption algorithms that was a serious candidate to be used in the quantum computing world has been defeated worryingly simply. The algorithm in question is called SIKE ...

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 ...

For Diffie-Hellman encryption, you want what is called a "safe prime," meaning a prime number p such that q = (p -1)/2 is also prime (IOW, a safe prime is the counterpart of a Sophie Germain prime).

Although most users don’t know it, their Web browser plays a key part in determining the strength of the ciphers used between their client and an HTTPS-protected Web site. Encryption ciphers used in ...

Twenty years before the Internet would create a need for it, a public-key cryptographic standard was discovered and patented by Whitfield Diffie, along with another student and a professor at Stanford ...
