Microchip has expanded the security capabilities of the KEELOQ authentication system. The KEELOQ 3 Development Kit demonstrates these enhancements to the KEELOQ system with a patented secure-learning algorithm that prevents differential power analysis attack techniques. Additionally the technology now supports 128-bit encryption keys, longer data transmissions and bi-directional communication authentication; and also supports alternative encryption algorithms, such as XTEA and AES.

The kit comes complete with a controller board containing a 28-pin 8-bit PIC16F886 Flash MCU, two programmable transmitter boards, one receiver board and a PICkit 2 programmer. All source-code files and application notes are also included. Examples include security systems (keypads, remote sensors and access control); remote keyless entry (automotive) and authentication applications (identity and property). The KeeLoq 3 Development Kit is available for $159.99.
