The HCSXXX Encoder family combines a 32-bit hopping code generated by a non-linear encryption algorithm, with a 28/32-bit serial number and 5 status bits to create up to a 69-bit transmission stream. The length of the transmission eliminates the threat of code scanning and the code hopping mechanism makes each transmission unique, thus rendering code capture and resend (code grabbing) schemes useless. The KEELOQ family of code hopping devices provide a simple yet highly secure solution for remote control locking devices, house keys, garage door openers and home security systems. The key is a proprietary, non-linear encryption algorithm that creates a unique transmission on every use.
