Microchip announces it has expanded the security capabilities of the patented 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 enhanced microcontroller-based encoder solution enables customisation, so that further security enhancements can be implemented over time.

The low-cost KEELOQ 3 Development Kit is designed to help engineers get up to speed quickly using PIC microcontrollers (MCUs) and provides everything needed to program, debug and develop secure authentication applications for a variety of markets. 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 PICkitTM 2 programmer. All source-code files and application notes are also included.

Enhancements over the KEELOQ II development kit enable a robust and reliable system design that is highly configurable and provides scalability across Microchip’s entire 8-, 16- and 32-bit PIC MCU portfolio, to address the needs of almost any secure authentication application. Examples include security systems (keypads, remote sensors and access control); remote keyless entry (automotive) and authentication applications (identity and property).
