Microchip Technologies, the "PIC" people, according to the grapevine is introducing smart card products apparently based upon Nanoteq's algorithm's. Microchip calls it "Keeloq Code Hopping". Bruce Schneier's short description of the Nanoteq algorithm (p 390 2nd edition Applied Crypto ) is not too favorable. I'm not sure how code hopping interacts or is used in the system. Can anybody shed further light on this subject and the viability of this cryptographic system?
