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). Finally, we discuss the choice of the signature parameters, in particular providing 70-bit security.
Keywords:
post-quantum cryptography, code-based cryptography, digital signature, Stern's scheme, Fiat-Shamir transform, provable security, EUF-CMA security.
