Abstract

This paper proposes a hardware structure and associated finite state machine designs sharing key scheduling circuitry to enhance the performance of the block cypher algorithm, HIGHT. It also introduces an efficient protocol applicable to RFID systems comprising the HIGHT block cipher algorithm. The new HIGHT structure occupies an area size small enough to accommodate tag applications. The structure yields twice higher performance them conventional HIGHT algorithms. The proposed protocol overcomes the security vulnerability of RFID tags and thereby strengthens the security of personal information.
