Microchip Technology, a provider of smart, connected, and secure embedded control solutions, has recently introduced Ultimate KeeLoq technology. KeeLoq code hopping technology is a royalty free solution developed by Microchip that enables designers to develop highly secure authentication applications for automotive, residential, personal and commercial markets. Example applications include Garage door openers, Tire pressure monitoring systems, Automotive Remote Keyless Entry (RKE systems), wireless sensors, Remote controls and more.
The Ultimate KeeLoq protocol is a timer-based solution offering enhancements to the Classic KeeLoq protocol 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 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 dual KeeLoq technology encoder, which provides a complete turnkey solution. The Ultimate KeeLoq protocol enables users to develop highly secure Remote Keyless Entry (RKE) authentication applications for a variety of markets, including security systems, automotive and identity and property authentication.
Microchip’s royalty-free and industry-proven KeeLoq hopping code technology is used worldwide by leading manufacturers to provide additional security to their applications.
