Secure Implementation of the SternAuthentication and Signature Schemes for Low-Resource Devices

摘要

In this paper we describe the first implementation on smart-card 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.
