Remote object authentication against counterfeiting using elliptic curves
Résumé
This paper aims to provide a remote fingerprint object authentication protocol dedicated to anti-counterfeiting applications. The corresponding security model is given. The suggested scheme is based on an Elliptic Curve Cryptography (ECC) encryption adding a mechanism to control integrity at the verification stage. The privacy constraint useful in many applications leads us to embed a Private Information Retrieval scheme in the protocol. As in a previous SPIE presentation, we begin with an optical reader. We drastically lower the amount of computation made at this stage.
