Embedded systems support more and more features. Authentication and confidentiality are part of them. These systems have limitations that put the public-key RSA algorithm at a disadvantage: Elliptic curve cryptography (ECC) becomes more attractive because it requires less energy and less area. A lot of attacks exploit physical access on cryptographic hardware device: power analysis attacks (SPA, DPA), or timing analysis attacks. The coprocessor presented here supports all critical operations of an ECC cryptosystem and has been secured against side channel attacks.
