Abstract

SM9-IBS is an industry standard for identity-based signature(IBS) algorithms issued by China in 2016. Although the IBS algorithms can be reduce the complexity of management of user keys, they have the problem of key revocation. In addition, the existing technologies aren't fully applicable to SM9-IBS due to its special algebraic structure of users' secret keys. Therefore, this paper proposed an efficient revocable SM9 identity-based signature(shorted as CS-SM9-RIBS) algorithm, which could quickly revoke and update the user's signature authority. This algorithm introduced a complete subtree, which was used by the key generation center(KGC) generated temporary signature keys for each legitimate user, so that only the signature generated by this key could pass the signature verification. In terms of security, the new algorithm was proven to be existentially unforgeable under adaptive chosen message and identity attacks in the random oracle model. In terms of efficiency, when the number of users in the system was large and the number of revoked users was small in the key update stage, the time cost of the KGC to update the user's signature key was much smaller than Boneh et al 's update technology.
