Abstract
A security controller (SC) restoration method is provided. The method includes: designating, by a master node, a node to which a backup SC belongs, where the master node includes an original DM or a backup DM; sending, by the master node to a first node, a message indicating the backup SC, where the message indicating the backup SC includes an identifier of the node to which the backup SC belongs; in a case in which a node to which an original SC belongs is disconnected, sending, by the master node to the first node, a message for enabling an SC function, for performing authentication, according to the message for enabling an SC function.

A security controller (SC) restoration method comprising:
- assigning, by a master node, a backup SC to a first node, wherein the master node is an original domain master (DM) node or a backup DM node;
- sending, by the master node, a first message regarding the backup SC to a second node, wherein the first message comprises an identifier of the first node to which the backup SC belongs;
- when a third node to which an original SC belongs is disconnected and the first and master nodes are different nodes, sending, by the master node, a second message for enabling an SC function at the first node;
- and
- when the master node is different from a node to which the backup SC belongs, the first node is different from both the master node and the node to which the backup SC belongs, sending, by the master node, a re-authentication request message to the first node.
A master node comprising:
- a processor configured to assign a first node to which a backup security controller (SC) belongs, wherein the first node comprises an original domain master (DM) node or a backup DM node;
- a transmitter configured to cooperate with the processor to
- (a) send a first message regarding the backup SC to a second node, wherein the first message comprises an identifier of the first node to which the backup SC belongs, and
- (b) when a third node to which an original SC belongs is disconnected and the first and master nodes are different nodes, send a second message for enabling an SC function at the first node, and
- (c) when the master node is different from a node to which the backup SC belongs, the first node is different from both the master node and the node to which the backup SC belongs, sending, by the master node, a re-authentication request message.
A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out operations including:
- assigning a backup security controller (SC) to a first node, wherein a master node is an original domain master (DM) node or a backup DM node;
- sending a first message regarding the backup SC to a second node, wherein the first message comprises an identifier of the first node to which the backup SC belongs;
- when a third node to which an original SC belongs is disconnected and the first and master nodes are different nodes, sending a second message for enabling an SC function at the first node;
- and
- when the master node is different from a node to which the backup SC belongs, the first node is different from both the master node and the node to which the backup SC belongs, sending a re-authentication request message to the first node.
A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out operations including:
- assigning a backup security controller (SC) function to a first node, wherein a master node is an original domain master (DM) node or a backup DM node;
- sending a first message regarding the backup SC to a second node, wherein the first message comprises an identifier of the first node to which the backup SC belongs;
- when a third node to which an original SC belongs is disconnected and the first and master nodes are different nodes, sending a second message for enabling an SC function at the first node by performing authentication according to the second message on the first node;
- and
- when the master node is the same as the first node, activating the SC function for performing authentication at the master node.
