Abstract
The present invention is directed toward secure access systems. Specifically, a method, system, and device are described that employ a synchronized pseudo-random number generator to secure communications between endpoints involved in a communication. If synchronization is lost between two devices, the two devices can regain synchronization by switching to use of a different pseudo-random number generator that is used for resynchronization instead of communications.
