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 ...

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’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 ...

The Firefox browser will now deny TLS connections to servers using weak Diffie-Hellman keys. Logjam was one of several downgrade attacks discovered in the last 18 months that could theoretically allow ...

This paper proposes a graphene-assisted bidirectional key exchange protocol that integrates terahertz (THz) physical-layer modulation with the Diffie–Hellman (DH) cryptographic framework, addressing a ...
