STRENGTHENING THE SECURITY OF NETWORK APPLICATIONS WITH SSL PROTOCOL

Hu Yan 1, Dong Mingchui 2 (1. Tsinghua University, Beijing 100084, China) (2. Institute of Systems and Computer Engineering, Macao, China)  
With the development of information technologies in power systems, it is becoming increasingly popular to use the Browser/Server architecture to implement network applications for data transmission with HTTP protocol. However, since HTTP protocol is open and information is transmitted in plain text, it is vulnerable to network attack. This paper describes common network attacks such as interception,modification, fabrication and interruption and demonstrates the process of information interception. Then the SSL's security features and structures of the handshake layer and record layer are dealt with. Finally three kinds of schemes including software configuration, proxy mechanism, and SSL developing kits are presented to strengthen the security of network application using SSL protocol in existing network application for power systems.
