SECURITY DEVICE AND METHOD FOR MANAGING AUTHENTICATED USER DEVICE

摘要

The present invention relates to a method for managing an authenticated user device of a security device. The method for managing an authenticated user includes a step of checking whether a user device required for an access to a network is an authenticated user device, and a step of allowing the user device to have access to a network server when the user device is an authenticated user device. The step of checking whether a user device is an authenticated user device includes a step of checking whether the user device is an authenticated user device by using one of an address determination protocol request/response message transmitted to/received from the user device and a medium control address obtained from the user device. A dynamic host setting protocol allocates an IP to the user device.
