Title:
The security of the code-based signature scheme based on the Stern identification protocol
Authors: Victoria Vysotskaya, Ivan Chizhov
Abstract:The paper provides a complete description of the digital signature scheme based on the Stern identification protocol. We also present the proof of the existential unforgeability of the scheme under the chosen message attack (EUF-CMA) in the random oracle model (ROM) under assumptions of hardness of syndrome decoding and hash function collision finding problems. Finally, we discuss the choice of the signature parameters and introduce a parameter set providing 80-bit security.
