In this dissertation, two new proxy signature schemes from bilinear pairing are proposed, which are all based on discrete logarithm problem on GDH group. In the first scheme, the proxy signing ability can be revoked during the period of validity. Then, the malicious signer can not sign messages any more. Moreover, in this scheme secure channels are not needed.

本文基于GDH群的离散对数问题结合短签名的特点设计了两个代理签名体制，第一个体制可以在证书的有效期内撤销代理签名权，从而防止不诚实的代理签名者继续签名，而且无需安全信道。
