In this scheme, the key updating algorithm is used by the original signer, so the security of the proxy signature key is promoted to a higher level.

该方案将密钥更新算法应用在原始签名者计算过程中，更有效增强了代理签名密钥的安全性。

Besides having the basic properties of the proxy signature, the new scheme prevents proxy misuse, original signer's forgery and public key substitution attack.

此外，该方案不仅满足代理签名的基本性质，还避免了代理权滥用、原始签名人伪造和公钥替换攻击。
