  • 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.

  • Publication number: 20200411924
    Abstract: A battery module includes a battery cell assembly having a plurality of battery cells, a sensing assembly which covers a front and rear of the battery cell assembly when mounted thereto, a module case which receives the battery cell assembly and the mounted sensing assembly, and a thermally conductive adhesive interposed between an upper inner surface of the module case and an upper side of the battery cell assembly. The sensing assembly includes a first busbar frame assembly positioned at the front of the battery cell assembly, a second busbar frame assembly positioned at the rear of the battery cell assembly, and a sensing wire which connects the first and second busbar frame assemblies and runs across the upper side of the battery cell assembly in a diagonal direction. The thermally conductive adhesive is disposed on two sides of the sensing wire.
