Abstract (in Japanese) (See Japanese page) 
(in English) One of crucial points for ubiquitous network is to keep the temporary security without relying on permanent network infrastructure. Considering a practical solution of ubiquitous security is a safety aware. high-performed single chip processor, the authors have exploited a multimedia stream cipher engine and its VLSI chip implementation by using standard cell CMOS chips supported by VDEC. In order to keep security, usability, speed, and power consciousness, the stream cipher engine takes a compact multicore architecture. Each core implements a double cipher scheme that covers RAC (random addressing cryptography) and data sealing. However, a former stream cipher engine was built in only one RNG (random number generator) per core, it has not always shown sufficient cipher strength. In order to solve this issue, two RNGs are built in per core that are provided for RAC and the data sealing. Then, the latest version of the stream cipher engine chip is developed by using a 0.18-m standard cell CMOS chip.
