Cryptography General Interview Question:

What is Authenticated Diffie-Hellman Key Agreement?

Submitted by: Administrator

The authenticated Diffie-Hellman key agreement protocol, or Station-to-Station (STS) protocol, was developed by Diffie, van Oorschot, and Wiener in 1992 [DVW92] to defeat the middleperson attack on the Diffie-Hellman key agreement protocol. The immunity is achieved by allowing the two parties to authenticate themselves to each other by the use of digital signatures and public-key certificates.
