Abstract(in English) Recently, almost every person has a mobile phone and notebook PC, and uses the Internet for sending and receiving several informations. Thus, mobile appliances need to apply private information security technology, especially cipher algorithm processing, for protection against the leakage of personal information. Additionally, low power dissipation and fast processing are also required-capability for mobile equipment. For improving processing speed, "bitslice implementation method" have been exploited to increase encrypting/decrypting parallelism. The encrypting/decrypting performance depend linearly upon the processing parallelism in the bitslice implementation. Conventional researches for bitslice implementation are often used several high performance processor, such as RISC processor and x86 processor. In this paper, we presents effective bitslice encryption method, which is used an ultra-compact single-board computer. In the AES implementation, the value of encryption throughput for parallel bitslice AES processing is about 2.7 times faster than that of the single AES implementation. Furthermore, the ultra-compact single-board computer can improve the performance per watt by a factor 10 in comparison to a conventional x86 processor.
