Title:
SYSTEM AND METHOD FOR UPDATING AN ENCRYPTION KEY ACROSS A NETWORK
Document Type and Number:
WIPO Patent Application WO/2015/073422
Kind Code:
A3
Abstract:
Systems and methods are provided for generating subsequent encryption keys by a client device (131)as one of a plurality of client devices (131 -134) across a network (1 10). Each client device (131 -134) is provided with the same key generation information and the same key setup information from an authentication server(120). Each client device (131 -134) maintains and stores its own key generation information and key setup information. Using its own information, each client device (131 -134) generates subsequent encryption keys that are common or the same across devices (131 -134). These subsequent encryption keys are generated and maintained the same across devices (131 -134)without any further instruction or information from the authentication server (120)or any other client device. Additionally, client devices (131 -134)can recover the current encryption key by synchronizing information with another client device.
