A major point in designing and evaluating vehicle security systems, either immobilizer or alarm systems, is to make them as much hard as possible to the understanding, the copying and the replaying of the coded signals used to activate/disactivate the anti-theft system. The main methods to encipher and decipher messages are discussed as well as their evolution because of the spread of electronics in to the vehicle and the increasing demand of higher safeness in an age of fast development of computer performances and people know-how. The close analogy between the needs of robustness and inviolability of activating/disactivating messages in vehicle security systems and the current existing data-transfer security items (banking transactions, medical data,etc.) is emphasized. The fitting and the implementation of high security algorithms by means of actual HW/SW architectures widely used in automotive applications is described.
