概要

• 論文の詳細を見る

• Although threshold key-recovery systems for the discrete log based cryptosystems such as the ElGamal scheme have been proposed by Feldman and Pedersen, no (practical) threshold key-recovery system for the factoring based cryptosystems such as the RSA scheme has been proposed. This paper proposes the first (practical) threshold key-recovery systems for the factoring based cryptosystems including the RSA and Rabin schemes. Almost all of the proposed systems are unconditionally secure, since the systems utilize unconditionally secure bit-commitment protocols and unconditionally secure VSS.
