车联网中面向服务的隐私保护群密钥管理方案
|
摘要
现有的采用密钥树结构的群密钥管理方案在降低群密钥管理开销方面不彻底,且没有考虑车辆的身份隐私.笔者提出一个面向服务的隐私保护群密钥管理方案,利用车辆假名绑定服务保护身份隐私,基于中国剩余定理设计群密钥因子,使服务群的成员能以一个模运算获得群密钥.对其进行分析表明:笔者方案比经典方案具有更高的安全性、较少的计算和通信开销.
Existing group key management schemes used the key tree based structures to reduce rekeying overhead.But it was not thorough and ignored the identity privacy of vehicles.A service-oriented privacy-preserving group key management(PVGKM)scheme was proposed in this paper.It used vehicles' pseudonyms to bind subscriptions for protecting the identity privacy of vehicles,and designed a group key factor based on the Chinese remainder theorem so that the service group members could get the group key with one modulo division operation.Security and performance analysis showed that the proposed scheme had higher security,less computation and communication cost than the classical schemes.
