摘要：This paper presents area-efficient hardware architectures of 64-bit block cipher KASUMI for network security and cryptographic applications. The proposed designs exploit the rolling characteristic of KASUMI to obtain a single round architecture with optimized KASUMI sub-function FO and key generation / scheduling scheme. The FO / FI function explores 2 × low area design implementations for S9 and S7 substitution functions. The first method formulates 16 × logic expressions of S9 / S7 into a single expression whereas the second scheme is based on the minimum utilization of S9 / S7 logic gates. Hardware implementation on ASIC (Application-Specific Integrated Circuit) 0.18 μm at 1.8V resulted in area-efficient KASUMI architectures consisting of 2487 and 2294 gates with throughput values of 32.4 Mbps and 4.6 Mbps respectively. A detailed performance comparison with existing KASUMI architectures yields that the proposed architectures are the most area-efficient KASUMI implementations till date. © 2018 IEEE.
