Research And Implementation Of Secure Access System For Power Mobile Terminal

With the rapid development of the construction of the smart grid and the mobile communication technology,more and more different types of mobile terminals need remote access to the electric power enterprise internal network,and a variety of business enterprises are expanding the business to the mobile terminal.However,it also brings new security issues,which are new challenges for electric power enterprise information security.How to ensure electric power enterprise information security,when mobile terminal remote access to enterprise internal network,has become a critical problem to be solved.Firstly,the present situation of electric power mobile terminal secure access is analyzed then point out that the security issues of mobile terminal remote access involves three parts: access terminals,access channels and the internal applications.Secondly,for the security problem,combine with the traditional terminal security access technologies,the electric power mobile terminal secure access system is designed.The idea of three-tiered defense is used.On the mobile terminal security,the security architecture of mobile terminal and role-based detection method are designed,in order to strengthen its own security capabilities and ensure the security of mobile terminals access.As for the data transmission security,through the improvement of SSL protocol,united with PKI technology,the SSL protocol based on PKI and SSL control protocol is proposed to ensure the security of data transmission channel.On the network application system security aspect,the network application system security defense system is designed and the security access control for the mobile terminal is carried out to ensure the security of network application system.Finally,some of function modules of the system are described in detail,and practical tests verified the function of them.In view of the practical application of a power enterprise,the production management system of electric power enterprise based on Andiord is developed.That it access power integrated control system by the mobile terminals secure access system,the mobile terminals secure access to the power integrated control system is implemented.In the view of the practical application of the project,the safety and reliability of secure access system for power mobile terminal is verified,which can effectively ensure the safety of the power integrated control systems and the information security of electric power enterprises.
