The Research Of Multi-source And Massive Data Security In Store-access In Power Grid Entertainment

With the arrival of the era of big data,power grid enterprise information technology is showing a trend,a variety of multi-mass data to the speed of a dozen TB.Since 2009,the construction of power grid enterprises in various independent business domain,the power grid enterprises in the assets,production,marketing,finance,human resources and the integration of six areas of the field of independent business subsystems,to provide a great business support.With the information management system information management system information data coverage and the life of all aspects,the existing computer data security has been unable to ensure that the multi mass data security storage and access technology.In order to solve the electric power enterprise in enterprise software security problem of insufficient,in this paper,the security of data storage and access to commonly used algorithms and techniques for in-depth analysis,for the enterprise information system provides a by AES for security encryption and decryption of data security deposit storage method,and the use of the role of control design to achieve the 4A platform for secure data access technology,provided comprehensive data security storage and access protection for enterprise information system.Firstly,this paper analyzes the related concepts of AES encryption and decryption algorithm,describes the Rijndael algorithm,the encryption and decryption of AES algorithm,the security analysis of AES algorithm,and introduces the application of AES algorithm,and introduces the related theory,which lays a theoretical foundation for the design of the paper.Secondly,according to the characteristics of enterprise application software,this paper studies and develops a new type of data security storage method,which is independent of the hardware device.It covers the needs of different users,so that the whole system can achieve the purpose of protecting the privacy of individual data at different levels.In this paper,we design a set of open source CA framework,which is used to realize the data security of the system,and ensure that the information is encrypted in the transmission process.This paper describes the overall design of the data storage,front end design and back-end design,to achieve the front and rear system security suite,digital signature,digital envelope,digital certificate acquisition,back-end database implementation,digital envelope analysis and digital signature verification function,and the end of the encryption and decryption process by EJBCA.According to the needs of enterprise application software in data security access,this paper designs and implements the enterprise 4A authentication system.The user identity and access rights are controlled by user's unified authentication and permission management.In summary,the enterprise level based on AES personal information security suite not only to achieve the system security but also to protect the safety of enterprise application,implementation of the unified authentication of enterprise application,enhances the system usability.
