Researching On Key Security Technology Based On The WAP Protocol

The mobile office system is a new series of office system, it came into being with the rapid development of communication technology, especially the wireless communication technology and the Internet technology. The mobile office system provides the enterprise the advantage for mordern management and the higher efficiency, the system could raise the efficiency, improve the office work.In this thesis, through the study on the WAP protocol, the risks of the moblie office system, and the existing security solutions, a security solution is proposed for the mobile office system. The solution uses the AES algorithm to encrypt the communication data between the servers and the mobile terminals in order to provide the confidentiality. It was programmed with java for the particular of the moblie office system. According to the application servers, the solutions uses the IDS to secure the servers. This solution does not take any modification to the underlying protocol and the network infrastructure, and it could be implemented with moblie terminals of poor resources.The work the author has done is:1. Study the WAP protocol, the risks of the moblie office system, and the existing security solutions. Propose a security solution for the mobile office system.2. Research the AES algorithm and the principles of its design. Implement the AES encrypt algorithm fit for the PCs and mobile terminials. Improve the efficiency of the algorithm with optimized method. Analyze the performance by the test experiment.3. Study the principles and the technology of the IDS. Research the snort system as the representative system. Propose a modified model by the study of the linchpin of improving the system. Install and improve the system based on the study. Analyze the performance by the test experiment.
