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 ...

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 ...

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 ...

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, ...

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 ...
