  • Patent number: 11075907
    Abstract: 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.
