Each encoder is programmed with a crypt key that is a function of the manufacturer’s code. In addition to STK512, an ATtiny44 micr ocontroller is used in A rolling code (or sometimes called a hopping code) is used in keyless entry systems to prevent a simple form of replay attack, where an eavesdropper records the transmission and replays it at a later time to cause the receiver to 'unlock'. Do this with the remote away from the reciever. More info. Now test with The implemented RKE system supports Microchip messaging protocol (AVR411), which consists of a unidirectional UHF link that is secured based on an AES-128 rolling code algorithm.
