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.

Abstract: A Tate Pairingbased appointed multireceiver 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.
Key words: Tate pairing, multireceiver encryption, IDbased signcryption , digital signatures
