本文对强代理签名进行了深入研究和探讨。
Strong proxy signature is researched and discussed in this paper.
安全分析表明它是一种弱代理签名方案，不属于强代理签名。
The analysis of security shows that it is a weak proxy signature scheme and does not belong to a strong proxy signature scheme.
该方案与其它方案相比，不仅更为高效，而且达到了强代理签名的安全性要求。
Due to the use of short signatures, the scheme is not only efficient, but also satisfies all the security requirements of the strong proxy signature.
分析表明所提方案能够满足强代理签名方案的安全需求，同时不需要使用安全信道。
Analysis shows that the proposed scheme satisfies all security properties of the strong proxy signature scheme and does not need a secure channel.
此外，新方案还满足强代理签名的所有性质，并且在原始签名者和代理签名者之间的通信可以不使用安全信道。
In addition, the proposed scheme satisfies all properties of strong proxy signature and doesn't need to use secure channel between the original signer and the proxy signer.
