Abstract
Systems and methods are provided for generating subsequent encryption keys by a client device as one of a plurality of client devices across a network. Each client device is provided with the same key generation information and the same key setup information from an authentication server. Each client device maintains and stores its own key generation information and key setup information. Using its own information, each client device generates subsequent encryption keys that are common or the same across devices. These subsequent encryption keys are generated and maintained the same across devices without any further instruction or information from the authentication server or any other client device. Additionally, client devices can recover the current encryption key by synchronizing information with another client device.
