| 摘 要： | So fur, the security of many proxy signatures has seldom been considered in a formal way and most of them cannot satisfy nonepudiation. In this work, a novel ID-based （Identity-based） proxy signature scheme is proposed by combining the proxy signature with ID-based public cryptography, and they formalize the notion of security for ID-based proxy signature schemes. And show that the security of the proposed scheme is secure. Compured with other proxy signature schemes, it does not need a secure channel. Thus, it is particularly suitable for the unreliable network computation environment. Finally, they extend proposed scheme to a proxy multi-signature which has the following advantages （1） the size of proxy multi- signature is independent of the number of delegating users; （2） the computation cost of proxy multi-signature only need two Weil paring.

| Abstract: | So far, the security of many proxy signatures has seldom been considered in a formal way and most of them cannot satisfy non-repudiation.
In this work, a novel ID-based (Identity-based) proxy signature scheme is proposed by combining the proxy signature with ID-based
public cryptography, and they formalize the notion of security for ID-based proxy signature schemes. And show that the security
of the proposed scheme is secure. Compared with other proxy signature schemes, it does not need a secure channel. Thus, it
is particularly suitable for the unreliable network computation environment. Finally, they extend proposed scheme to a proxy
multi-signature which has the following advantages 1 the size of proxy multi-signature is independent of the number of delegating
users; 2 the computation cost of proxy multi-signature only need two Weil paring.
