摘要： PROBLEM TO BE SOLVED: To provide a method and a system wherein a home agent decrypts an encrypted payload part of an ICMP error packet and transfers processes the ICMP error packet to a correspondent node. SOLUTION: The home agent (HA) 1 for managing positional information associated with movement of mobile nodes receives an IP packet 205 transmitted from the correspondent node (CN) 8 to a mobile node (MN) being a mobile destination, applies encryption 206 to the IP packet and transfers the resulting packet to the mobile node through mobile tunneling. When the IP packet does not reach the MN, a router or the like in a network transmits the ICMP error packet 208 to the HA 1. The HA 1 uses a destination address denoting a transmission destination of an ICMP part of the ICMP error packet to apply transmission decryption 209 to the encrypted payload part of the ICMP error packet and transfers the ICMP error packet resulting from applying de-capsulating processing 211 to the tunnel packet to the CN 8.

摘要： PROBLEM TO BE SOLVED: To prevent duplication of SPI of SAs when a communication subject apparatus establishes a plurality of IPsecSAs with the same objective communication apparatus by utilizing an IKE. SOLUTION: The subjective communication apparatus stores the ID of an objective communication apparatus in an IKE phase 1, and stores an SPI for establishing the IPsecSA from the objective communication apparatus in an IKE phase 2 together with the established IPsecSA so that the SPI is correlated to the ID of the objective communication apparatus. In the IKE phase 2, if the same objective communication apparatus requests to establish the IPsecSA by SPI, the apparatus rejects establishment of the IPsecSA when the already established IPsecSA remains, and establishes the IPsecSA when the already established IPsecSA has been deleted.

摘要： PROBLEM TO BE SOLVED: To reduce an amount of traffic of a communication network by reducing an amount of signals for location registration of MN (Mobile Node) when a plurality of HAs (Home Agents) exist in a home network.
SOLUTION: The HA connected to the same home network identifies neighboring search signals from other HAs by holding a link layer address of the HA connected to the same home network, when the neighboring search signals are the ones in discovery of duplicated addresses to be executed in the case that the location registration is requested in the HA, recognizes that the location registration of home addresses in the neighboring search signals is performed, deletes a binding cache held in the self device and avoid response to the neighboring search signals. In addition, loss of a replay defense function of Binding Update is avoided by taking compliance by sequence numbers by imparting the sequence numbers to the neighboring search signals.

摘要： PROBLEM TO BE SOLVED: To maintain a communication environment by a VPN (Virtual Private Network) without performing the reset of an established IPsec (security architecture for IP) tunnel, or the like, even when a terminal in the VPN separates from an IP (Internet Protocol) network of the terminal itself. SOLUTION: A network system constitutes the VPN by establishing the IPsec tunnel for performing dynamic routing based on an IP prefix between a first tunnel terminating device in a first IP network and a second tunnel terminating device in a second IP network. When a terminal in the second IP network separates from the second IP network, information regarding the separation is added to information for determining an IPsec tunnel route of the first tunnel terminating device. In addition, the information regarding the separation is added to the second tunnel terminating device or the subordinate router of the second tunnel terminating device. The separation can be responded by transferring packets by longest-coincidence retrieval with the devices. COPYRIGHT: (C)2011,JPO&INPIT
