Abstract

A remote control group transmitter (1) stores an encryption key uniquely associated with the remote control group. The transmitter decrypts an encrypted group-specific site code in a teaching radiation signal. The site code is then used to generate the encryption key for operation of a shared group function. The transmitter, in use, encrypts the discrimination value and the hopping index with the encryption key. The serial number is transmitted, but is not encrypted A receiver of the group decrypts the encrypted code to determine the discrimination value and hopping index. The receiver validates a new transmitter by receiving and decrypting two encrypted codes in quick succession and checking that the serial numbers are the same and the second hopping index is valid with reference to the first hopping index.
