Design And Implement Of Frequency EOC System And Research Of Its Security Mechanism

In recent years, the national policy of supporting triple play increased intensity, and the workboost into the substantive stage. At present, the triple play of many experimental cities has beeninitiated. It will promote the industry technology progress. And it will also promote structuraladjustment of whole electron information industry, and enhance the informatization level in ourcounty. Finally, it will bring convenience to majority users.As an important access technology of the triple play, EOC technology will be widely spreadand applied. So the research of efficient design and security mechanism of EOC system, inparticular the research of the security issues will inevitably become the key of influence the futureactual performance.This thesis researches several aspects on key technologies of the EOC system security: First ofall, in view of the efficiency and accuracy problems of EOC system's hardware and softwarestructure design process, designed and implemented the security and efficient EOC system based onthe HomePlug AV technology, and designed the sub-modules of system memory pool and RawSocket data pool, and improved the telecommunication efficiency and accuracy between centraloffice equipment and terminal equipment of the EOC system. Secondly, in the aspect of securityauthentication mechanism and data flow encryption of EOC system, this thesis proposes the EOCsystem authentication method based on SSL protocol and the method of using hybrid encryptionscheme for EOC traffic encryption, and carry on the analysis of its security. The integrity andconfidentiality of the data could be guaranteed in the transmission process, and the danger ofterminal MAC address counterfeit could be solved effectively. Finally, in the aspects of EOCsystem access control research, combined with the actual project development process, researchedthe access control strategy of the EOC system from the perspective of the VLAN classification, andthis thesis presents a double tagging VLAN partition method of EOC system based on businessclassification, described the implementation process, and analyzed. This method can divide andrestrict the business flow, and solve the problem of unauthorized use of accounts and sharedaccounts to improve the security of the EOC system.
