Atmel Corporation (Atmel) announced the adoption of open source licensing released AES-128 encryption standard based on a complete anti-theft device (immobilizer) protocol stack. The company offers the industry first anti-theft device protocol stack open-source vendors, the move underlines its commitment to promoting the development of the global automotive electronics market, designed to help engineers shorten their time to market.
Since almost all of today alarm remote keyless entry (RKE) / passive keyless entry (PEG) system components, the different IC vendor interoperability between devices and the real strength of the device the same security council capacity (peer-reviewing) becomes extremely important. Atmel has decided to open source license and launch anti-theft device protocol stack, which allows the provisions of all the participating enterprises in the legal system and provide recommendations within the review.
Atmel AES-128 anti-theft device protocol stack is the first semiconductor supplier to allow different devices to achieve interoperability between the open source stack. The traditional solution uses the existing closed source or proprietary communication protocol layer, which not only hindered the car manufacturers to adopt the procurement strategy for a variety of vendors, but also in the event of quality problems because of technical constraints affecting production.
alarm protocol stack defines the key and the base station device from the physical layer to the AES encryption engine for all the necessary layers, while the physical layer is based IC manufacturers to use all mature, full-duplex (Full-Duplex, DFX) mode can achieve backward compatibility, making the most of existing base stations and key devices to seamlessly support the protocol stack.
In addition, this protocol stack with high compatibility, according to the needs of specific applications to optimize all key parameters, and, authentication mechanism (single or multiple re-certification), the question and the response length, data rate and modulation way, the number keys, AES computation time can be configured according to specific applications to optimize turnover (turn-around) time with the lowest coupling factor. The agreement also specifies the key learning process, you can choose to use an additional transport key to further enhance the security of the supply chain. Using this mechanism, car manufacturers on the production line in between the keys and car initial “pair” to encrypt communications.
SPICE using CMMi and automotive product development process of global automotive engineering technology solutions provider KPIT Cummins, has been released by Atmel in 2010, all new RKE / PEG product line offers production-ready of this agreement ( production-ready) implementations, all Atmel AVR-based RKE and PEG devices are used to achieve this agreement, high-quality program at the factory programming.
protocol definition files can be obtained from the Atmel web site application (free registration), all applications will be accepted, and open source license is included in the definition file. . Doc9195.pdf family_id = 692
