“…For example, Cheng et al [20] constructed an identity-based group signature scheme by using bilinear pairing. Zhang and Ye [21] proposed an identity-based threshold group signature based on the discrete logarithm problem. Ma [22] gave a generic construction of the identity-based group signature.…”

Group signature can provide the privacy-preserving authentication mechanism for the blockchain. In the traditional blockchain privacy-preserving scheme based on the group signature, there is only one group manager to revoke the anonymity. Thus, the traditional scheme will have single point of failure and key escrow problems. To solve these problems, we propose a privacy-preserving scheme in the blockchain based on the group signature with multiple managers. Our scheme is constructed based on bilinear pairing and the technique of distributed key generation. Finally, we analyze the application of the proposed scheme in the field of blockchain-based provable data possession (PDP), as well as the correctness and security of the scheme.
