【摘要】：在“厂网分开、竞价上网”的大背景下，电厂竞价上网数据直接关系发电调度计划的制定，进而影响电厂的经济利益，绝对不能泄露给竞争对手。另外，发电调度计划不仅用于指导各个电厂进行高效、合理、安全生产，而且影响电能质量和电网的正常运行。因此，，必须确保电厂接收到正确的调度计划并按质按量完成，不会否认或抵赖。本文研究了基于私有云存储的数据安全问题，并在搭建小型的云存储系统之后，完成了以下几方面的工作：首先，为了满足对海量数据存储的需求，课题研究了云存储关键技术。详细介绍了云存储的体系结构和开源云计算平台Hadoop的分布式文件系统HDFS，并对HBase的体系结构、逻辑模型和物理模型进行了研究。其次，对访问控制机制进行了深入分析，重点研究了RBAC模型，设计了一个基于主客体标签的分层访问控制模型。通过在云存储平台中的实现，证明了该模型能够有效保障云存储平台中各电厂发电调度计划的访问控制，并且其性能损耗基本可以忽略，满足实时性要求。最后，本课题对信息完整性的检测措施进行了研究，深入研究了基于椭圆曲线的数字签名算法。文中利用Matlab工具进行仿真实验，证明了该算法的高效性。
[Abstract]:Under the background of "separation of power plants and power plants, bidding for the Internet", the bidding data of power plants is directly related to the formulation of the power generation scheduling plan, and thus affects the economic interests of the power plants, and must not be leaked to the competitors. In addition, the power generation scheduling plan is not only used to guide the efficient, reasonable and safe production of each power plant, but also affects the power quality and the normal operation of the power grid. Therefore, it is necessary to ensure that the power plant receives the correct dispatching plan and completes it according to quality and quantity, without denying or denying it. This paper studies the data security problem based on private cloud storage, and after building a small cloud storage system, it completes the following work: Firstly, in order to meet the requirement of mass data storage, the key technology of cloud storage is studied. The architecture of cloud storage and the distributed file system HDFS of open source cloud computing platform Hadoop are introduced in detail, and the architecture, logic model and physical model of HBase are studied. Secondly, the access control mechanism is deeply analyzed, the RBAC model is studied, and a hierarchical access control model based on the subject-object label is designed. Through the implementation in cloud storage platform, it is proved that the model can effectively guarantee the access control of power generation scheduling plan of power plants in cloud storage platform, and its performance loss can be basically ignored to meet the real-time requirements. Finally, this paper studies the information integrity detection method, and deeply studies the digital signature algorithm based on elliptic curve. In this paper, the Matlab tool is used to carry out the simulation experiment, and the efficiency of the algorithm is proved.
