Abstract: This paper proposes two Strong Designated Verifier Signature (SDVS) schemes based on two post-quantum key agreement protocols. One protocol is based on a problem about an isogeny between supersingular elliptic curves. The problem is hypothetically strong against a quantum computer. Another protocol is based on the computational difficulty to solve multivariate algebraic equations of high degree. Our proposals are the first instantiations of a basic design idea about SDVS that are potentially secure against a quantum computer.
Keywords: SDVS; strong designated verifier signature; quantum computing; isogenies; multivariate algebraic equations; key agreement protocols; computer security.
