This paper presents a concept for an UHF tag supporting cryptographically strong authentication which is based on the Rabin-Montgomery public key cryptosystem in accordance with the framework of ISO/IEC 29167-1. It uses an easily computable long integer square operation for the public key encryption of a tag ID record. Only a legitimate interrogator who is in possession of the private key can decrypt this message and retrieve the authentic tag ID. A working prototype based on a standard FPGA is shown which demonstrates the feasibility of the proposed cryptographic function.
