MSP-system: Mobile Secure Passport System to detect Malicious Users

One of problems with mobile networks is that malicious users can enter networks and launch attacks from the networks. To tackle the issues, in this paper, we propose the MSP-system: Mobile Secure Passport System. The objective of the MSP-system is to detect malicious mobile users and to prevent them from participating in mobile networks. The MSP-system is consisted of the MSP (Mobile Secure Passport) and the MSP-gateway. The MSP, which is a secure mobile device, preserves users´ history information. The MSP-gateway detects malicious users by checking the history information about network activities when users try to log into networks. Thus, the MSP-system can prevent malicious users from attacking in mobile networks. Through simulation experiments, we have confirmed the effectiveness of the MSP-system.
