Ad Hoc网络中基于身份的加密方案

摘要

In order to solve the separation between personal communication key and group communication key in traditional Ad Hoc network,we propose a encryption scheme in Ad Hoc network which is based on identity-based cryptosystem, and it has ability of cluster-level and revocation mechanism. In the scheme, the sender only use one key to specify the access permissions of the encrypted data by using the cluster level,and it can revoke any subset of the members to complete the personal communications or designated members of the group communication.%为了解决传统Ad Hoc网络中个人通信密钥与组通信密钥相分离的问题,以基于身份的密码体制为基础,提出了适用于Ad Hoc网络的具有簇的层次和撤销机制的加密方案.在该方案中,利用簇的层次将组通信密钥融入用户的个人通信密钥中,使发送者只需使用同一密钥就可以指定加密数据的访问许可,同时可撤销任意的成员子集,以完成个人通信或对指定成员的组通信.
