On the study of service security model for privacy using global user management framework

GUMF (global user management framework) that is proposed in this research can be applied to next generation networks such as BcN (broadband convergence network), it's QoS guaranteed security framework for users can solve the present Internet's security vulnerability. GUMF offers anonymity for users of the service and uses the user's real-name or ID for management of service and it's technology can realize secure QoS. GUMF needs a management framework, UMS (user management system), VNC (virtual network controller) etc. UMS consists of a root UMS in country dimension and local UMS in each site dimension. VNC's network security equipment includes VPN, QoS and security functions etc., and it achieves the QoSS (quality of security service) and CLS (communication level switching) functions. GUMF can offer safety in bandwidth consumption attacks such as worm propagation and DoS/DDoS, IP spoofing attack, and most current attacks such as abusing of private information because it can offer the different QoS guaranteed network according to user's grades. User's grades are divided by 4 levels from Level 0 to Level 3, and the user's security service level is decided according to the level of the private information. Level 3 users that offer bio-information can receive secure network service where privacy is guaranteed. Therefore, GUMF that is proposed in this research can offer a profit model to ISP and NSP, and can be utilized by strategy for secure u-Korea realization.
