Abstract
A method and system for dynamically changing password-keys in a secured wireless communication system includes initiating a password key change, generating a new password key, embedding the new password key and a password key indicator in a first message, encrypting the first message using an old password key, storing the new password key, sending the formatted encrypted first message over a wireless communication system, receiving a subsequent second message, and decrypting the subsequent second message using the new password key.
