In this paper we propose a model for anonymous traceability scheme with unconditional security. The model uses two subsystems: an authentication code with arbiter (A3-code) and an asymmetric traceability with unconditional security. We analyse security of the system against possible attacks and show that security parameters of the system can be described in terms of those of the two subsystems. We give an example construction for the model.
