Security Of Transparent Data Exchange In Information Integration System

In the integrated application of information environment and need information from multiple sources of incremental extraction or data query, these sources of information is distributed in different network environment of computer, so the application to adapt to a variety of environmental data exchange, has completed the information communication system integration platform expanded phase separation of application and communication environment of data communication gateway. And do not consider the system so produced no safety risk, the paper will from the identity authentication, data encryption, communication platform in the original transparent data exchange based on, to prevent untrusted site access to the system, ensure data privacy and to prevent data from being tampered with in the security module.At first, the thesis analyses the original transparent data exchange structure and existing problems, in order to prevent the site may have been from outside or within the network, a malicious user registration, from the resource management center access to the site within the system of communication resource, which makes the system in an important number occupies by leak risk, this paper in exchange platform added layer of security to ensure the security of data transmission.For registered site, by resource management center certification services for them distribute certificate, used in data exchange, ensure that the data is from the correct sender and receiver.When data transmission, in order to prevent eavesdropping, tampering and other attacks in the network, the need to encrypt and sign important data.Finally, several security requirements are integrated into the security layer to be applied to the data exchange platform, which provides a secure transmission based on transparent data exchange for the integrated system.
