Design of a low-power asynchronous elliptic curve cryptography coprocessor

Le résumé fourni par la source

The current evolution of mobile devices and networked pervasive computer systems, such as wireless sensor networks, demand more and more functionality while consuming a minimum amount of energy. Security is one important need within such networked systems. With respect to this, the asynchronous design style is an accepted way of hardening crypto-cores against side-channel attacks. In this paper, we show a case study of designing a low-power asynchronous processor for elliptic-curve-cryptography. Therefore, we provide the theoretical base of this crypto-technique and a description about the applied designflow. For the evaluation, a layout has been created and compared with a synchronous implementation. The results show that even for a larger asynchronous implementation the power consumption is only one third of the synchronous one.
