针对CCN网络的加密技术研究

提出并设计了基于内容中心网络的新一代网络技术，这种网络可以解决网络发送端授权过重、网络架构可信度低、新应用部署困难等一些问题．并基于这种新型网络设计了一种文件传输策略，同时结合了基于属性加密等一些加密方法，弥补了CCN网络中兴趣包（Interest）与数据包（Data）传输中的安全性．在传输内容属性文件时，采用本文介绍的“策略的加密过程”后进行具有网络路由器参与的文件共享传输．用户（解密方）在路由器缓冲数据包中得到文件后采用本文的“策略的解密过程”解密即可得到原始文件．

Research on Encryption of CCN

In this paper, a project utilized a novel generation network technology- content centric networking（CNN） system is proposed, which to solve the problem such as over- limited authority of senders, low reliability of network architecture, difficulty in the deployment of new application and the like. Based on CNN system, a new strategy of network file transfer combining with attribute - based encryption is designed, which may enforce the security of interest packets and data packets transfer on CNN system. In this method, content property files by the encryption algorithms will be introduced by this paper before the file sharing transfer via network routers. And then users （decrypting parties） will decrypt the files received from the buffering packets of network routers with the decryption algorithms demonstrated in this paper and get the original files.
