Abstract:
We discuss several methods that can be used to accelerate the verification step of ECC-based signature schemes. We show how to obtain a 40% efficiency improvement of ordinary ECDSA signature verification and even a factor 2.4x efficiency improvement when ECDSA certificate verification is combined with the key computation step in Diffie-Hellman-based protocols, such as static-ECDH and ECMQV. This challenges the conventional wisdom that with ECC-based signature schemes, signature verification is always considerably slower than signature generation and slower than RSA signature verification. Results apply to all prime curves standardized by NIST, the NSA 'Suite B' curves, and the so-called Brainpool curves.
