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 ...

Researchers have devised a way to place undetectable backdoors in the cryptographic keys that protect websites, virtual private networks, and Internet servers. The feat allows hackers to passively ...

I'm trying to understand how public key authentication works and with tools such as ChatGPT I'm able to resolve how it works; the server keeps a tab of "authorized" public keys and uses them to ...

Today we’re going to talk about how to keep information secret, and this isn’t a new goal. We’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard ...

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 ...

Researchers have uncovered a flaw in the way that some servers handle the Diffie-Hellman key exchange, a bug that’s somewhat similar to the FREAK attack and threatens the security of many Web and mail ...

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 ...

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, ...
