This paper intends to provide information about up-to-date performances of smart-card arithmetic coprocessors regarding major public-key cryptosystems and analyze the main tendence...
: Smart card secure channel protocols based on public key cryptography are not widely utilised mainly due to processing overheads introduced in the underlying smart card microproce...
This paper proposes different low-cost coprocessors for public key authentication on 8-bit smart cards. Elliptic curve cryptography is used for its efficiency per bit of key and ...

A sensitive point in public key cryptography is how to protect the private key. We outline a method of protecting private keys using cryptographic camouflage. Specifically, we do ...
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 ...
