Engineering aspects of hyperelliptic curves

We are able to close the performance gap between elliptic curve cryptosystem and hyperelliptic curve. We mainly considered engineering aspects of the cryptographic primitive hyperelliptic curves. We introduce three main contributions, that improve the overall acceptance of HECC as one of the public-key primitives for future applications:

  1. improvement of the group operation;
  2. implementation of HECC on general and embedded processors;
  3. development of HECC coprocessor.
In addition to the work done considering HECC, we developed a metric to compare the performance of cryptographic primitives on every available processor.
