%X Matsushita et al.proposed a traitor tracing scheme with flexible user revocation,which was a symmetric scheme,and did not provide multiple-service capability.An improved scheme was proposed by using Oblivious Polynomial Evaluation(OPE) and service parameter.In this improved scheme,such features of Matsushita's as flexible user revocation,black-box tracing and security remained,and other advantages such as providing multi-service and preventing traitors from repudiation(asymmetry) were added.The whole capabilities of the improved scheme were better than that of Matsushita's.
