Research On Data Security Technologies In Network Operating System

Since the reform and development of virtualization technologies, Cloud computing based on virtualization technologies attracts the industry’s attention. Cloud computing is the new computing concept after the distributed computing and the grid computing. The famous IT companies, such as the Microsoft, Google and other companies have proposed their own cloud computing solutions. The network operating system is a kind of distributed system which is based on cloud computing and virtualization technologies. There are some problems in the network operating system, such as the large-scale data, the complex structure and so on. However, data security issues are not taken appropriate attentions. This problem directly degrades system services.This article is based on the National "Core electronic device, general advanced chip and fundamental software product" sub-project,"New Network Application Mode Network Operating System". By this experimental platform, we analyzed and researched on the critical data of the network operating system. The author analyzes data types and data characteristics in the network operating system platform, and analyzes the system’s data encryption, data integrity and so on. According to the analysis of data security, we proposed the user access method which is based on RSA algorithm and random data, and the data security which is based on MD5and RSA algorithm, and data access protection which is based on network address. Finally I optimize the data security method and proposed a network data flow prediction liner model based on human periodically behavior.
