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 ...

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 realm of secure communications, data exchange and secret key agreement algorithms are pivotal for establishing confidentiality and ensuring the integrity of information transmitted over ...

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 ...

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 ...

Hot on the heels of Diffie-Hellman upending the cryptography applecart in 1976 came three more crypto newcomers that further revolutionized the field: Ron Rivest, Adi Shamir, and Leonard Adleman. The ...

Author Nick Sullivan worked for six years at Apple on many of its most important cryptography efforts before recently joining CloudFlare, where he is a systems engineer. He has a degree in mathematics ...
