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 ...

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 ...

The inventors of public key cryptography have won the 2015 Turing Award, just as a contentious debate kicks off in Washington over how much protection encryption should really provide. The Association ...

This article is excerpted from Privacy on the Line: The Politics of Wiretapping and Encryption, Updated and Expanded Edition, by Whitfield Diffie, vice president and ...

Asymmetric encryption (public-key algorithms) involves a key pair: a public key for encryption or signature verification and a private key for decryption or signing. This category includes RSA, Diffie ...
