摘　　要：对李发根提出的基于身份门限代理签密方案进行分析,指出该门限代理签密方案存在明显错误,导致其方案不可行,并提出一个新的基于身份门限代理签密方案。该方案不但同时具有前向安全性和公开验证性,而且新方案在效率方面更具优势。This paper analyzed the identity-based threshold proxy signeryption scheme proposed by Li Fa-gen, and pointed out that there were obvious errors in his scheme, which cause the scheme to be infeasible. Then this paper proposed a new identity-based threshold proxy signcryption scheme. This scheme not only can fulfill both public verifiability and forward security, but also has great advantages in efficiency.
