Microchip recognizes that the highly talented researchers have been successful at a theoretical attack of a block cipher. However, the KEELOQ security system implementation involves much more than just the cryptographic algorithm. The researchers’ claims that vehicles can be stolen, based on their cryptographic findings related to the KEELOQ algorithm, are incorrect due to several mistaken assumptions.

Microchip does not believe a public debate on how to steal vehicles benefits consumer security. In addition, for reasons of customer confidentially, Microchip cannot disclose specific information regarding the errors in the claims being made.

Customers with questions related to this matter should contact their local Microchip sales office. A worldwide directory of sales offices can be found on the Microchip Web site at www.microchip.com/sales.-Microchip
