An e-passport is a passport that includes biometrics information and ID by an RFID chip inserted internally. An e-passport not only prevents forging of ID but also makes rapid progress at immigration. The number of forged passports is increasing worldwide; therefore, to strengthen national security against international terrorism or crime, nations all over the world are now driving to bring in electronic passports. The epassport can prevent passport forgery and increase stability by intensifying the personal verification procedure. The fundamental weakness of a wireless channel, which is the instability of the link, limitation of physical protection of each node, there involves a high risk in the reality of the connection between nodes. In addition, there is no guarantee of security because of the fundamental weakness of the sensor node itself in hardware restriction. This paper designates the deduced security weakness and demands that could occur in an electronic passport, and suggests a direction for security service based on safe key distribution and an authorization technique. The proposed public key method to hash lock on reverse functional difficulty of a one-direction hash function to detect and verify a damaged electronic passport increases stability and creates resistance on capture. And to block illegal information on an authentication server, the kill Tag method is executed. The proposed method provides the high efficiency of a multileader management method through a mutual authentication mechanism and a multi-leader management method between the passport and the Reader. Therefore, the method can increase security by protecting from reprinting, wiretapping and meson efficiently.
