Abstract

Electronic cash is an important method for internet payment. In order to make sure the controllable anonymity, scholars before brought in the TTP to the E-cash as the way to prevent illegal usage. Based on the e-cash system model, which uses the Juels’ trustee-based tracing mechanism, this paper brings in the process of Schnorr zero-knowledge identity verification to improve it and analyses its security in the end.
