%X In this paper a threshold secret sharing scheme to identify cheaters is proposed by using authentication codes.The performance of the scheme is discussed. The results show that in the scheme the valid shareholders not only can identify the impersonation of an adversary, but also are able to detect the cheating of some valid shareholders, in particular one honest shareholder is able to detect the cheating of the other participants forming a coalition, and the information rate of the scheme is higher than that of others.
