A novel design of the KASUMI block cipher using one-hot residue number system

The KASUMI block cipher is used for the cellular communications networks and safety of many wireless standards. Third generation cellular network technology (3G) permits to transmit information, voice and video at very high data rates never seen before that will revolutionize personal communications and information exchange. On the other hand, Residue Number System (RNS) is a modular representation and is evidenced to be serviceable equipment in many applications which need high-speed computations and high-performance components. RNS is a non-weighted and integer number system that can support secure, highspeed, low-power, parallel and carry-free arithmetic. For attaining the most performance a technique is declared that named "One-Hot Residue Number System". The propagation delay of this implementation is just one transistor. In this paper, synthesizing the KASUMI encryption algorithm and One-Hot RNS for improving the KASUMI features are presented. In this document, we represent a novel design of the KASUMI block cipher using OHRNS. The goals of this design include strategies to reduce delay, power consumption, hardware and lastly power-delay product. © IDO SI Publications, 2012.
