摘要
通过构建基于CPK体制的IBE方案,试图从根本上解决CPK体制的合谋攻击问题,并根据该方案建立了有效的基于身份的加密体制。
According to the process of constructing an identity-based encryption scheme based on combined public-key scheme,it proposes the definition of general IBE-CPK scheme,the definition of bilinear map,the definition of complexity assumption,and the notion of security.Based on above all,it suggests a new identity-based encryption scheme.By analyzing the conspiracy attack on CPK,the consequence is that this new scheme defenses this attack.
