文章摘要
随着个人和企业数据量的迅速增加和云计算技术的成熟,越来越多的用户选择将数据存储在云服务器上,并委托云服务器对数据进行处理。然而,数据是企业的无形资产,用户担心云服务器将自己提交的数据泄露给未授权的第三方,这会导致企业或个人承担一系列的风险,甚至造成经济或名誉的损失。首次提出一种抗双方泄露抵赖的云端数据托管协议,该协议利用数字水印方法将托管信息隐藏在数据中,可抵抗服务方数据泄露抵赖和委托方诬陷服务方泄露数据的攻击。对该协议进行模拟实现,实验结果证明了协议的正确性,且性能上已接近实用性要求。
Abstract
With the proliferation of data and the maturation of cloud computing technology, more and more users choose to store data on the cloud server and commissioned the cloud server to process the data. However, the data is the intangible assets of the enterprise, users do not want the cloud server to submit their own data leaked to unauthorized third parties, which will lead enterprises or individuals to bear a series of risks, and even cause the loss of economy or reputation. Therefore, for the first time, we propose a new protocol that cannot be denied by both parties in the event of data leakage. This protocol used the digital watermarking method to hide the managed information in the data, which can prevent the server from denying the data disclosure and the client from falsely accusing the server of leaking the data. The protocol was simulated and implemented. The experimental results show that the protocol is correct, and the performance is close to the practical requirements.
