Abstract

A system and method for generating reproducible session keys in a wireless messaging system. The session key is generated based on a hash of a message itself, optionally concatenated with additional information. Since the local server stores the message, it can easily regenerate the same session key in response to each MORE request. The method of the invention can be implemented with the stored original message, a public key, and an algorithm for generating the session key based on a hash of the message.
