摘要:

针对共享在公共云环境的用户数据因所有权与管理权分离而导致的用户隐私泄露问题,结合对称加密算法、属性加密算法和副本定位技术,提出一种云环境下的数据多副本安全共享与关联删除方案,对用户数据进行加密等处理封装成副本关联对象(RAO,replication associated object),随后将RAO共享到云服务商,建立副本关联模型对 RAO 所产生副本进行管理并实现关联删除。分析表明方案是安全与有效的,能够对用户共享的数据及其副本进行安全共享与关联删除,有效保障了数据多副本的隐私安全。

Abstract:

In order to protect the privacy of data stored in public cloud environment,a security sharing and associated deleting scheme for multi-replica was proposed,which was based on symmetric encryption algorithm,attribute encryption algorithm and replica location technology.In this security scheme,the user’s data was first encrypted and encapsulated into the replication associated objects (RAO),then the RAO was shared in cloud service provider and managed by the replica correlation model.The comprehensive analyses show that the scheme is security and effective,and is able to support the data security sharing and associated deleting for multi-replica to protect the data privacy.

Key words: cloud environment, user privacy, multiple-replicas, security sharing, related deletion
