An end-to-end security communication method includes, when receiving a security key generation request packet from a first host, generating, by a communication controller, a security key for end-to-end security communication between the first host and a second host, transmitting the generated security key to each of the first host and the second host, and setting a forwarding rule for transmission of a packet destined for a Media Access Control (MAC) address of the first host or a MAC address of the second host to a first switch and a second switch connected respectively to the first host and the second host. According to the end-to-end security communication method, the communication controller performs the process of generating a security key that will be shared between hosts using Software Defined-Networking (SDN), so that MAC security communication technology can be applied to communication between hosts belonging to different networks.

A mobile network is disclosed in which there exists a Mobile Node (MN), the MN is managed by a first Access Router (AR), and there exists a second AR with a subnet different from the first AR. A method is provided for the MN performing a fast handoff from the first AR to the second AR, which includes receiving a Routing Advertisement (RA) message of the second AR from the first AR, generating an IP address to be used in the second AR using the RA message of the second AR if the MN recognizes that it should perform a handoff from the first AR to the second AR, performing a trigger for using the generated IP address if the movement to the second AR is completed, and transmitting/receiving a Correspondent Node (CN) and data using the IP address.
