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

I 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.
