Distribution and authentication of public keys using random numbers and diffie-hellman public keys

摘要

A system to exchange and authenticate public cryptographic keys between parties that share a common but secret password, using a pair of random numbers, a pair of Diffie-Hellman public keys computed from the random numbers and the password, a Diffie-Hellman symmetric secret key computed from the Diffie-Hellman public keys and the random numbers, and hashed values of arguments that depend upon these elements.
