At the core of Diffie-Hellman is the discrete logarithm problem, which makes it computationally difficult for attackers to intercept and decode the shared secret key exchanged between two parties.

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.

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 ...

How keys are distributed is vital to any encryption system. Find out how to do it with the Diffie–Hellman key exchange and using public-key cryptography.

The new Logjam attack on export-grade Diffie-Hellman key exchange can downgrade the security of connections and allow attackers to decrypt traffic.

The researchers focus on Diffie-Hellman key exchange, a method for two parties to securely share a cryptographic key that was first published in 1976 and is widely used.

Men behind Diffie-Hellman key exchange receive top computer science prize Pioneering work 40 years ago lead to PGP, TLS, and all your fav crypto protocols.

Diffie and Hellman are being honored for developing the first instance of public-key cryptography back in the 1970s. Called the Diffie–Hellman key exchange, the protocol established a way to ...
