Abstract

Hitag2 is an encryption algorithm designed by NXP Semiconductors that is used in electronic vehicle immobilizers and anti-theft devices. Hitag2 uses 48-bit keys for authentication and confidentiality, and due to that feature it is considered an insecure cipher. In this contribution we present a comparison of low cost technologies able to break a known protocol based on this cipher in a reasonable amount of time. Building on top of these solutions, it is possible to create an environment able to obtain Hitag2 keys in almost negligible time. The procedure can be easily expanded in order to consider other protocols based on the same cipher.
