【摘要】 云计算模式中,数据存储在云服务器提供商,用户需要验证返回数据的正确性和完整性。高效验证是云计算模式中数据安全研究的重点,针对这个问题,本文提出了一种基于子树(Sub_MB)的验证方法。该方法构建MerkleB树存储相关信息,通过计算最小验证子树验证数据正确性和完整性。与MB、EMB和ASB方法相比,该方法验证效率提高15%左右。更多还原

【Abstract】 In the model of cloud computing,data are stored in the cloud service providers,users need to verify the authectication and completeness of the returned data.Efficient verfication are becoming an important aspect of the cloud computing.We propose an approach based on subtree,that constructs an Merkle B tree to store the related information,and verify the authentication and completeness of data through computing the least validation subtree.In contrast with the previous work such as MB and EMB,this approach increases the verification rate by 15%.更多还原
