First the elliptic curve digital signature algorithm is improved by avoiding the time consuming inversion operations in its signature generation and verification Then a proxy signature scheme is devised based on the improved elliptic curve digital signature algorithm, which satisfies all of the security requirements Proxy signature is a signature scheme that an original signer delegates his/her signing capability to a proxy signer, and then the proxy signer creates a signature on behalf of the original signer The scheme that allows a proxy signer to generate a proxy signature on behalf of two or more original signers is called a proxy multi signature scheme All of the proxy multi signature schemes that have been proposed are based on the ordinary discrete logarithm problem Here a proxy multi signature scheme based on the elliptic curve discrete logarithm problem is proposed for the first time When using this new scheme, proxy multi signature can be generated and verified more efficiently, and the length of the proxy multi signature is shortened greatly

首先对椭圆曲线数字签名算法 (ECDSA)进行了改进 ,方法是避免其签名生成和签名验证过程中费时的求逆运算 然后在此改进的椭圆曲线数字签名算法基础上 ,设计了一个代理签名体制 ,该体制满足代理签名的所有安全要求 所谓代理签名体制是指原始签名人把自己的签名权利委托给代理签名人 ,然后代理签名人代表原始签名人产生代理签名的体制 允许代理签名人代表多个原始签名人产生代理签名的体制称为代理多签名体制 ,目前所提出的代理多签名体制都基于一般群上的离散对数问题 在此首次提出基于椭圆曲线离散对数问题的代理多签名体制 ,极大地提高了代理多签名生成和验证的效率并缩短了代理多签名的长度

This paper proposes 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 and it allows a group of original signers to authorize a proxy signer on behalf of the original signer group. The second type called a multi-proxy signature scheme, means an original signer can authorize a group of proxy signers to sign on behalf of him/her. The third type is called multi-proxy multi-signature scheme because in this scheme multiple original signers delegate their signing capability to a group of proxy signers. As preparation, authors present the multisignature based on Hess's ID-based signature scheme which the latter two types of proxy signature schemes will use. This is the first identity-based multisignature scheme from bilinear pairings. The most important point about the new schemes is that the sizes of the proxy signatures in all these three types are independent of the number of original signers or proxy signers. The verification of them is similar to that of ordinary proxy signatures.

作者提出三类新的来自双线性配对的涉及多个签名人的代理签名体制 .第一类称为代理多签名体制 ,它允许一组原始签名人授权给一个代理签名人来代表他们 ;第二类称为多代理签名体制 ,意思是一个原始签名人可以授权给一组代理签名人来代表他 (她 ) ;第三类称为多代理多签名体制 ,因为在此体制中 ,多个原始签名人把他们的签名权利委托给一组代理签名人 .作为准备 ,作者提出了基于Hess的基于身份签名体制的多签名体制 ,这是第一个来自双线性配对的基于身份的多签名体制 ,后两类代理签名体制将用到它 .关于作者提出的新体制 ,最重要的一点是在这三类体制中 ,代理签名的长度均独立于原始签名人或代理签名人的个数 .它们的验证也与一般的代理签名类似 .

Two forgery attacks presented on a proxy multi-signature scheme based on elliptic curves discrete logarithm problem proposed by Ji and Li. Using these forgery attacks, anyone of original signers can produce a valid proxy multi-signature. Furthermore, a new modified and secure proxy multi-signature scheme based on elliptic curves discrete logarithm problem were proposed.

对Ji和Li的基于椭圆曲线离散对数问题的代理多签名体制提出了两个伪造攻击。利用这两个伪造攻击,任何一个原始签名人都能伪造出一个有效的代理多重数字签名。并对Ji和Li的代理多签名体制进行了改进,提出了新的安全的基于椭圆曲线离散对数问题的代理多签名体制
