摘　　要：纪家慧等人利用双线性配对提出了三类代理签名体制:代理多签名、多代理签名和多代理多签名,但这三类代理签名方案都是不安全的。分析说明了这三类代理签名存在伪造攻击,任何一个原始签名人或代理签名人都可以伪造合法的代理签名。Ji proposed three new types of proxy signature schemes that deal with multiple signers from bilinear pairings. The first type is called a proxy multi-signature scheme, the second type is called a multi-proxy signature scheme, and the third type is called multi-proxy multi-signature scheme. But the three proxy signatures are all insecure. Forgery attacks are presented on the proxy signatures. Using the forgery attacks, anyone of original signers or proxy signers can produce a valid proxy signature.

关 键 词：双线性配对 代理签名 伪造攻击
