摘　　要： 本文利用认证码构造一种可防止欺诈的秘密分享方案。此方案不仅可防止非法者的假冒,也可防止子密合法拥有者的欺诈,特别是可防止某些子密合法拥有者形成团伙对另一合法者的欺诈,且数据利用率较高。 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.
