    Hardware Implementation of an Attack on KeeLoq Cipher

  • Original language description

    This thesis is concerned with KeeLoq cipher, mainly the hardware implementation of the attack on the cipher. Requirement for the application implementation is to have ample known plaintexts and corresponding ciphertexts. In this thesis I present implementation of two possible attacks by brute force, which may be used on a system without memory, and another attack method using the Meet-in-the-middle technique, which requires memory. When comparing the results with software implementation, hardware one ofmeet-in-the-middle attack comes off slightly slower. The reason is that the attack needs to work with memory quite often and other logic does not take much time.
