Abstract
As an IEEE 802.11-based mobile computing system has been established as the base structure of high-speed wireless network, interest in mobility and security of mobile terminal has increased. To reinforce security, 802.1x and 802.11i using EAP were used in standardized instrument. But it was found to be unsuitable for real time multimedia service because of the time delay. In this paper, we suggest Fast and Secure Handover (FSH) scheme which minimizes time delay in handover authentication process and prevents MITM (Man in the Middle) attack. This scheme carries out re-association process which is necessary for high-speed handover using Inter Access Point Protocol (IAPP) and Old-MSK. To make existing 802.1x-based user certification procedure suitable for high-speed handover, the terminal and pre-handover-accessed Old-AP make Rough-AP to prevent MITM. To do this, Old-AP uses the Old-MSK-used encrypted method which was used to encrypt MAC information of the mobile terminal and Old-AP. Hereby, FSH has been developed to become high-speed handover which has the 802.1x-supported security level and the skill of preventing MITM. In this paper, by simulation (NS-2), we confirmed the superiority in streaming service such as decreased handover time delay and VoIP.
