Research On The Security Middleware Of Supporting Mobile Multimedia Communications

Along with developing of the computer and communication technologies, computer application has obtained the unprecedented popularization and the Internet also has gained the rapid extension; The main Carrier of the information transmission has been already from wired to wireless.the information transmitted by the wireless network has already been from simple voice messages, text messages to complex multimedia style. The E-commerce entered the field of wireless. All of these have facilitated people's life enormously and greatly promoted the development of information society at the same time. However, the problem of information security is unsolved until now, because this problem involves many factors. For instance, the cryptology theory which provides the information security is very difficult to understand and the application environment is also very complex and so on. Especially in the wireless network environment, security problem is outstanding, which involves the question is more complex. For example, wireless interface's openness, the network bandwidth is limited, wireless terminal computation ability is insufficient, and throughput, large-scale, efficiency, performance, cost and so on.
