ABSTRACT:
A packet transfer scheme for realizing a control of a packet inspection device to pass only packets from those mobile computers that can be recognized as authenticated among non-management target mobile computers that had moved inside the network, to outside the network. A packet inspection device judges whether a passing of a packet transmitted from a mobile computer other than own management target computers to outside the own network is permitted or not, according to a mobile computer identification information contained in the packet, and sends a message indicating a refusal of the passing of the packet to the mobile computer when the passing of the packet is judged to be not permitted; and then transfers the packet when the passing of the packet is judged to be permitted; and also checks whether a user information regarding a user of the mobile computer satisfies a prescribed condition or not, upon receiving a message requesting a key information for generating the mobile computer identification information from the mobile computer, and returns a requested key information to the mobile computer when the user information satisfies the prescribed condition.
