Secure personalization using proxy cryptography

Abstract

In this paper we describe new secure personalization schemes using proxy cryptography. We first introduce the context of a large scale smart card application such as an electronic purse, the current personalization schemes and the security requirements. We recall the notion of proxy cryptography and we consider an actual proxy cryptosystem based on ElGamal public key encryption. With this proxy cryptosystem we setup new security schemes for smart cards personalization and we show that they are more secure, flexible and cheap than existing ones.
