Secure implementation of the stern authentication and signature schemes for low-resource devices

Abstract

In this paper we describe the first implementation on smartcard of the code-based authentication protocol proposed by Stern at Crypto'93 and we give a securization of the scheme against side channel attacks. On the whole, this provides a secure implementation of a very practical authentication (and possibly signature) scheme which is mostly attractive for light-weight cryptography. © IFIP International Federation for Information Processing 2008.
