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
