Abstract: A deniable ring signature scheme allows a ring member to confirm or disavow that he is the signer of the ring signature via a protocol without a trusted third party. It balances privacy protection and controllable supervision, which has a wide range of applications. In order to improve and enrich commercial cryptosystems, this paper proposes a deniable ring signature scheme based on SM2, a standard digital signature algorithm, which realizes the functions of confirmation and disavowal of a signa... More
