一种新的基于身份的代理签名方案
New ID-based Proxy Signature Scheme
摘要
Abstract
Through the security analysis of an ID-based proxy signature scheme (Journal of Harbin Institute of Technology, 2008, No2), this paper points out it is unsafe and suffers from forgery attack launched by PKG.PKG not only can counterfeite proxy-authorization, but also can forgery a valid proxy signature.An improved scheme based on the property of original scheme is proposed and its security weakness is overcome.In the new scheme, the power of PKG is limited and the benefit of signer is protected, so it is more secure and efficient.关键词
