摘 要: | IBC虽然避免了复杂的身份认证和庞大的密钥管理问题,但由于IBC的密钥托管机构PKG掌握着主密钥s,而用户的私钥都是藉由s通过一个公开的私钥算法来生成,因此一旦主密钥s泄露或PKG不诚实,则用户的一切信息都将暴露,再无安全性可言。为了解决这个问题,该文提出了一种基于身份的混合加密方案。

Mixed encryption scheme based on identity |

Abstract: | IBC while avoiding the complicated identity authentication and the huge key management problems, but as a result of the IBC key escrow agency PKG holds the master key s, and the user's pri-vate key is by s through a public private key algorithm to generate, so once the master key s leak or PKG dishonesty, all the information of the user will be exposed, again with no security. In order to solve this problem, this paper proposes a hybrid encryption scheme based on identity. |
