For the secure transmission of information in the 3G mobile communication system , the paper briefly describes the significance of the 3G mobile communication system gateway technology , network security importance and gateway technology development are described , and highlights based on 3G security Gateway and AAA mechanisms solutions . Provides a new idea for the 2.5G to 3G transition . Design a of 3G security gateway system , which consists of a combination of data security access to the proxy and AAA solutions . Data secure access to proxy the system proxy access to data , WAN , including within the system , to solve the security problems . Compression and transmission of data , and can be done to improve the speed of data transmission . Data network transmission AAA mechanisms , information encryption , user authentication and other security measures , international popular DES standard encryption algorithm . Data security access to the gateway system , to solve the above safety problems , and are easily added to the information system , without increasing the complexity of the system . On this basis , this paper discusses the design and realization of the various parts of the 3G gateway system . Including the realization of the http proxy , https proxy , telnet proxy and AAA functions . The security gateway system mainly uses encryption and authentication technologies , to identify authorized technology , drawing on the AAA solutions . Encryption and authentication of the system design is widely used and mature SSL technology . The system is under in J2SDK development environment , using the popular web programming language Java implementation . The study on the security gateway technology in 3G mobile communication context , there is not a lot of related articles and comprehensive exposition , the subject of this study is novel and unique role in promoting 2G to 3G transition .
