For FPGA based coprocessors for elliptic curve cryp-tography, a significant performance gain can be achieved when hybrid coordinates are used to represent points on the elliptic curve. We provide a new area/performance trade-off analysis of different hybrid representations over fields of characteristic two. Moreover, we present a new generic cryptoprocessor architecture that can be adapted to vari-ous area/performance constraints and finite field sizes, and show how to apply high level synthesis techniques to the controller design. 1
