Abstract
System and method for providing secure communications is provided. Initially, an exchange protocol, such as a password-authenticated key exchange protocol, is used to create a shared secret. From the shared secret, two keys are created: a utilized key and a stored key. The utilized key is used to encrypt messages between nodes. When it is time to replace the utilized key to maintain security, the stored key is utilized to encrypt messages for generating/distributing a new shared secret. The new shared secret is then used to generate a new utilized key and a new stored key. This process may be repeated any number of times to maintain security.
