This paper proposes a group signature scheme with a tracing mechanism that limits the tracing ability of tracers based on their attributes and decentralizes the tracing key generation method. Thus, no other party than the attributes satisfying tracer can identify the signer. The proposing scheme answers the single point of failure of the tracing mechanism in the existing group signature schemes. On the other hand, the multiple tracers setting of the proposing scheme reduces the tracing workload that the single tracer had, and provides selection flexibility for users to choose a tracer for their signatures based on tracers’ attributes. This paper discussed the related security definitions against outsiders and honest but curious authorities.
