AUTOMATIC SETTING OF SECURITY IN COMMUNICATION NETWORK SYSTEM |
摘要 |
<p>A communication network system has a plurality of sub-networks interconnected to one another, at least one mobile node having a care-of address dependent on a sub-network currently connected thereto and a home address independent of the connected sub-network, and a home agent. Upon detection of a sub-network to which the mobile node is connected, t he mobile node determines a security method corresponding to the sub-network from among security methods held in a node-side security application management table as a security method used for ensuring the security for use r data communicated between the mobile node and a home agent associated therewith. Then, the sub-network is notified to the home agent through a mobile node network signal. The home agent determines a security method corresponding to the sub-network from among security methods held in an agent-side security application management table as a security method used for ensuring the security for user data communicated between the home agent and the mobile node managed thereby.</p> |
