Pairing computation is more complicated compared to that of other popular public-key cryptosystems. Efficient implementation of cryptographic pairing, both software- and hardware-based approaches, has thus received increasing interest. In this paper, we focus on hardware implementation and present the design of Hydra, an energy-efficient programmable cryptographic coprocessor that supports various pairings over fields of large characteristics. We also present several implementations of Hydra, among which the smallest only uses 116 K gates when synthesized in TSMC 90 nm standard cell library. Despite the extra programmability, our design is competitive compared even with specialized implementations in terms of time-area-cycle product, a common figure of merit that provides a good measure of energy efficiency. For example, it only takes 3.04 ms to compute an optimal ate pairing over Barreto-Naehrig curves when the chip operates at 200 MHz. This is certainly a very small time-area-cycle product among all hardware implementations of cryptographic pairing in the current literature. © 2014 Springer International Publishing. |
