摘　　要： 借鉴身份签密理论,利用超奇异椭圆曲线上Tate对的特性,提出一种高效指定多接收者签密方案,为具有多名合法接收者的签名问题提供了解决途径.此方案不仅保持了基于身份加密的优点,具有签名多向性,而且其抗攻击性好,执行效率高,整个签密过程只需1次Tate对计算,随着指定接收者人数的增多,方案的效率优势会更加明显. A Tate Pairing-based appointed multi-receiver signcryption scheme is presented, in which some characteristics of Tate pairing are used. The new scheme offers a good way to solve the problem of signature with a lot of appointed receivers. Additionally, this scheme is simply designed and easily implemented. Only one pairing computation is needed in it to sign a single message for all appointed receivers. As a result, the efficiency gain of the new scheme is huge especially when there are a large number of recipients.
