The Analysis Of Data Security Algorithm For Wireless Communication Of Electric Power Automation

With the rapid development of comunication techinique of electric power automation, the requirement of network information security has been improved continuously. First the data transmission character of electric wireless system is analyzed. Then, by taking into account the development of electric comunication system, It presents a solution for data encryption and secret key management. It takes different algorithms to encrypt each layers of protocol according to every character of wireless communication mode. In addition, the project apply in the firewall and authentication thchnologies. It doesn't only prevent the unsafe service and disabled user from the system, but also prevent the invador from disgusing as legal user from stealing and distorting the data inside. So the system secure performance has been improved on network layer.Finally the encryption solution's performance has been analysized, the result indicates that the solution has improved effectively the information security performance.At the end of dessertation, the main problems of the research are summarized. The futher work is pointed out as well.
