Abstract
A method of securely transferring data from a transmitter to a receiver which includes the steps of at the transmitter encrypting data which at least in part is based on timer information at the transmitter, to form a transmission word, transmitting the transmission word to the receiver, at the receiver decrypting the transmission word, validating the transmission word by comparing the transmitted timer information to predetermined information at the receiver; and when a valid transmission word is received adjusting the said predetermined information.
