Asymmetric cryptography or public-key cryptography is cryptography in which a pair of keys is used to encrypt and decrypt a message so that it arrives securely. Initially, a network user receives a ...

On Tuesday, a team of computer scientists released a report (.PDF) documenting cryptographic problems with the Diffie-Hellman key exchange, a popular algorithm used by Internet protocols to agree on a ...

In a post on Wednesday, researchers Alex Halderman and Nadia Heninger presented compelling research suggesting that the NSA has developed the capability to decrypt a large number of HTTPS, SSH, and ...

It seems like we just got over the Heartbleed vulnerability, but there’s another major flaw with SSL called “logjam” that affects a number of fundamental Web protocols. The bug affects an algorithm ...

Programmers Whitfield Diffie and Martin E. Hellman, who developed the first form of cryptography for the internet era, have been awarded this year’s Turing Award. Named after famed British ...

It’s actually possible for entities with vast computing resources – such as the NSA and major national governments – to compromise commonly used Diffie-Hellman key exchange groups, so it’s time for ...

Martin Hellman achieved legendary status as co-inventor of the Diffie-Hellman public key exchange algorithm, a breakthrough in software and computer cryptography. That invention and his ongoing work ...

Implementing Internet key exchange (IKE) capabilities in standalone ASICs housing IPSec and other security tasks may appear to be a benefit to designers on paper. However, in real implementations, ...
