Research On Application Of Network Information Security In Mobile-phone Banking System

With the development of communication technique and the technique of networksafe, the mobile banking service has enriched the meaning of bank system service.Established in the technique of network safe, this paper conducts the design ofsecurity architecture model to the system of mobile banking service, analyzes theproblem of core security protection such as the client program compiler, informationtheft, Software tamper and virus detection. At the same time, through the SSLprotocol, the data is insured not to be cut up or wiretapped in the communicationbetween Mobile phone client and server and improves the safe of mobile bankingservice system from the terms of structure, application and communication.Firstly, this paper studies the general model of the safe information network ofmobile banking service. In the basis of safe, performance and security, it designs themodel of mobile banking system. From outside to inside, this model includes fourparts, that is, public access areas, DMZ service, application service area and thebackground core service area. By this way, it ensures the safe of inside networkeffectively on the whole.Secondly, from the aspect of client application, this paper makes the safetyprotection on the information theft, Software tamper and virus detection by using thethe technique of code obfuscation, randomly generated graphics keyboard, andinstalling the virus library.Finally, from the angle of the mobile phone client and server communication, thedata is encrypted and tested in the transport layer by using the SSL protocol and thedata can be ensured safe in this way. Through analyzing attack of middleman and theguarding method, the SSL authentication and RSA algorithm can be implemented.Through the analysis of experiment, this paper proposes the client securitytechnology and some methods such as encryption and verification algorithm, whichare better in the term of complexity. These technology and methods have a good theexecution efficiency. At the same time, the safe structure model in this paper has aneffective shielding and tracking to the attack. According to the secure protocol, wecan complete the safe system structure based on the network and deal with all kindsof safe threats.
