Theory and application of computationally independent one-way functions: Interactive proof of ability - Revisited

Sabyasachi Dutta and Kouichi Sakurai

Abstract: We introduce the concept of computationally independent pair of one-way functions (CI-OWF). We also provide two rich classes of examples of such functions based on standard assumptions. We revisit two-party interactive protocols for proving possession of computational power and existing two-flow challenge-response protocols. We analyze existing protocols for proof of computation power and propose a new two-flow protocol using CI-OWF based on square Diffie-Hellman problem.

Category / Keywords: cryptographic protocols / one-way functions, zero knowledge proof, computational independence, proof of computation ability
