Abstract
The disclosed technology provides a system and method of synchronizing cryptographic operation between a transmitter and a receiver. A transmitter can communicate encrypted data to a receiver according to a first communications protocol, and communicate a transmitter number and a portion of the encrypted data to the receiver according to a second communications protocol. The receiver can be in communication with a memory space containing locations that are each associated with an encrypted data and that can contain a previous receiver number. The receiver can receive transmitted encrypted data and an associated transmitter number and can search the memory space to find a location wherein the encrypted data associated with the location is entirely, or in part, the same as the transmitted encrypted data. When such a location is found, the receiver can compare the transmitter number with the previous receiver number stored in the location.
