Toward Quantum-Resistant Strong Designated Verifier Signature from Isogenies
Xi Sun, Haibo Tian, Yumin Wang · 2012
This paper proposes a strong designated verifier signature (SDVS) based on a recently proposed mathematical problem. It consists in searching for an isogeny between super singular elliptic curves. The problem is hypothetically strong against a quantum computer. This makes our proposal the first SDVS scheme that may be secure against a quantum computer.
