Ultimate KeeLoq® technology is a timer-based solution offering enhancements to the classic KeeLoq structure such as industry-standard AES-128 block cipher, programmable 32-bit serial number, programmable 128-bit encryption key and KeeLoq Secure Learn Mode (128-bit seed). It incorporates a timer-driven message counter that increments continuously, independent of events, to provide a better, more secure solution. The time-keeping functionality provides additional protection against capture and replay attack techniques.
The entire structure is available in the MCS3142 dual KeeLoq technology encoder, which provides a complete turnkey solution. The Ultimate KeeLoq protocol enables you to develop highly secure Remote Keyless Entry (RKE) authentication applications for a variety of markets, including security systems, automotive and identity and property authentication.
Our proprietary, royalty-free and industry-proven KeeLoq hopping code technology is used worldwide by leading manufacturers to provide additional security to their applications.
