KeeLoq® Technology

Introducing Ultimate KeeLoq

Ultimate KeeLoq is a new timer based solution offering enhancements to the

ultimate-keeloq

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 messages counter which continuously increments, 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 providing a complete turnkey solution. The addition of our new Ultimate KeeLoq Protocol provides the customer the ability to develop highly secure authentication applications for a variety of markets such as security systems (keypads, remote sensors and access control); remote keyless entry (automotive) and authentication (identity and property) applications

Microchip Technology has had a long history as a major supplier in the security industry primarily utilizing our proprietary, royalty-free KeeLoq Hopping Code Technology, an industry proven technology used worldwide by leading manufacturers, to provide additional security to their applications for more than 15 years.
