摘要:

越来越多的用户愿意把数据存储在云存储系统中,数据安全是云存储系统面临的关键问题,为了保证存储在云中数据的完整性、有效性,数据持有性验证(PDP)就显得尤为重要。为了验证云存储服务提供商是否完整地存储了用户的数据,基于不可否认PDP(NRPDP)方案提出了一种新的数据持有性验证方案。该方案基于公有验证和私有验证,可以同时对云存储中服务提供商与用户的可信性进行验证,满足了验证的不可否认性。理论证明了该方案的不可否认性,实验验证了各阶段运行时间效率比现有的单一的公有验证方法或私有验证方法更优。

关键词: 云存储, 不可否认, 数据持有, 公有验证, 私有验证

Abstract:

More and more users choose to transfer their applications and data into the cloud.Data security is a key issue for cloud storage systems.To ensure the integrity and validity of the data stored in the cloud,provable data possession (PDP) scheme is particularly important.In order to verify whether the cloud storage service provider had stored the data of the user completely,a scheme on the basis of NRPDP (non-repudiable PDP) was improved and extended,and a data retention scheme based on public authentication and private authentication was proposed.The scheme can verify the trustworthiness of the service provider and the user in the cloud storage at the same time,which satisfies the non-repudiation of the verification.The theory proves the non-repudiation of the proposed scheme.The experiment proves that the efficiency of each stage is better than that of the existing single public verification method or private authentication method.

Key words: cloud storage, non-repudiation, provable data possession, public verification, private verification
