This paper presents the issues associated with remote entry authentication for the automobile industry. Authentication is the process of validating the source of a remote entry command - it is essential part of vehicle security. Early remote entry systems used fixed user identification codes for authentication. Fixed codes may be intercepted and played back, therefore current systems use continuously changing codes. The most popular of these codes, based on linear pseudorandom number generators (PRNGs), are not very secure. The codes are predictable from intercepted messages. The design of a secure remote entry product depends on the number and type of security threats. Various threats and their consequences are reviewed.
