ABSTRACT OF THE INVENTION A process and system for applying public key cryptography to electronic lock systems (20), is disclosed. The data area (102) of the message which is to be transmitted is encoded as a digital signature, then is unsigned at the lock (30). The process separates the security function from the message and permits the use of a highly flexible protocol for controlling the lock (30).
