基于身份的抗密钥泄露加密系统的设计与实现

1984年Shamir提出的基于身份的加密方案简化了公钥生成和分发的工作,解放了公钥证书,但该方案存在密钥托管、公钥撤销、执行效率等问题。针对这些问题,在VC＋＋6.0的环境下,有效利用PBC工程中定义的大数结构,在不依赖随机神谕模型的基础上,设计并实现了抗密钥泄露IBE加密系统。与其他加密系统相比,该系统计算效率更为高效,且支持接收者匿名。由于该加密系统拥有较好的防御入侵能力,在网络安全通信、web应用服务、电子商务、电子政务等方面存在着良好的应用前景。

Design and Realization of Leakage-Resilient Identity-Based Public Key Encryption System

1984,Shamir proposed an identity-based encryption scheme,which simplifies the work of generating and distributing public key.So don＇t need public key certificate any more.However,there are some problems like key escrow program,the public key revocation,the efficiency and other issues.To solve these problems,in the environment of VC＋＋ 6.0,without relying on the random oracle model,design and realize the leakage-resilient system based on the structure of large numbers defined in PBC project.Compared to the other encryption systems,it calculates more efficiently and allows anonymous receiver.Since the encryption system has a superior ability to resist invasion,there is a good prospect of application in the field of safe network communications,web application service,electronic commerce,electronic government affair and so on.
