Abstract :
This paper compares implementations of elliptic and hyperelliptic curve cryptography (ECC and HECC) on an FPGA platform. We use the same low-level blocks to implement the basic operations and we choose the bit-lengths so that both systems have equal security levels. The results are in favor of HECC. Our HECC implementation is slightly larger than ECC, but at the same time around 35% faster
