Code-Based Identification and Signature Schemes in Software
Abstract
In this paper we present efficient implementations of several code-based identification schemes, namely the Stern scheme, the Véron scheme and the Cayrel-Véron-El Yousfi scheme. We also explain how to derive and implement signature schemes from the previous identification schemes using the Fiat-Shamir transformation. For a security of 80 bits and a document to be signed of size 1 kByte, we reach a signature in about 4 ms on a standard CPU.
