Data Security

The combination of cloud computing and big data can be said to be a perfect match. Large data requires a flexible computing environment, which can be extended quickly and automatically to support massive amounts of data. The infrastructure cloud can deliver these requirements precisely. 　　But whenever we talk about cloud computing, we can't avoid the following questions: What is the cloud security strategy for big data? When referring to cloud security policies in large data use cases, we hope that any security solution will provide the same flexibility as the cloud without impacting deployment security. When transferring large data to the cloud, the following four ...

The arrival of the big data age, let "data namely assets" become a new global trend, the national competition focus is shifting from the scramble for capital, land, population, resources/energy to the contention for large data, the large data subversive change global strategic pattern, international security situation, state governance structure and resource allocation mode, caused great economic change. For China, "overtaking" will be realized only when large data is raised as a major national development strategy, and the level of modernization of national governance system and governance ability is upgraded. The strategic significance of large data technology is not in mastering huge data information, but in ...

Design of HDFs hybrid encryption protection Scheme Liang Sheng Qin Song Lei How to solve the security problems in cloud computing effectively is the key to the development of cloud computing industry. Aiming at the security problem of the Hadoop cloud computing system in data sharing, a hybrid encryption protection scheme based on RC4 and RSA is adopted, which is closely combined with the characteristics of the Hadoop cloud computing system in the process of cloud storage data sharing, and it can realize the security sharing of the data, and both the confidentiality and the efficiency. Design of HDFs hybrid encryption protection scheme

Cloud-based Intelligent meter user form privacy protection Dream Yin Maoqi Mathilda Wenhong Intelligent Power System, the rapid development of massive data storage and computing requirements are more and more high, so that its integration with cloud computing becomes inevitable. But access to cloud computing systems inevitably brings data security problems. Aiming at the user information privacy protection of intelligent electric meter system, this paper introduces a trusted third party based on data combination privacy mechanism, and protects the user's privacy of smart meter system by using data block storage and block-relation obfuscation technology. And put forward a block information Form system, in the block storage environment to implement the number ...

IT industry has different views on cloud computing, it is still one of the hottest IT vocabulary in recent years. What exactly is cloud computing, and how does it help us to focus on enterprise R&D informatization?
