Abstract (in Japanese) (See Japanese page) 
(in English) Asynchronous bundled-data transfer circuits use delay elements as a strobe signal which indicates the stable state of the corresponding combinational circuit. Its delay value is always larger than that of the critical path in the combinational circuit. If it is constant as well as the clock signal of synchronous circuits, the current and the electromagnetic wave of the target devices show the same characteristics when they perform the same functions. Thus, they cannot tolerate side channel attacks. On the other hand, their characteristics can be varied by using random delay elements even if they perform the same functions. In this paper, we propose the circuit structure of random delay elements and present tamper-resistant asynchronous circuits.
