Messaging Middleware To Support The Secure Transmission Of Information, Research And Realization

This thesis analyses the characteristics of middleware and distributed application. Some solutions based on MOM are given to solve the problems of the message transmission mode, data security, data transmission reliability and data format.The new MOM OpenEDMQ subjects to JMS is brought out with the help of JMS API produced by SUN inc. OpenEDMQ adopts two kinds of communication modes PTP and Pub/Sub.In PTP mode, queues are the intermediate storage which ensures the communication synchronic or asynchronous. Pub/Sub mode makes the communication be anonymous by topic aassociates components.The security and reliability of data transmission always draw the user's attention most. To ensure the data is never stolen or modified by someone maliciously in transmission, thereby, all of the data to be delievered on the Internet is firstly encrypted with triple DES, and then compressed, which reduce the transmission flux and make it reliable and in time. The compressed messages are attached behind the message header and the message properties which are defined in XML format and transfer them to a server, then the server will pick up the messages from the head of it and put them into destination.Finally, the skills that are required to realize this system are summarized, and something that are immature and unrealized are discussed, the later work is pointed out.
