Abstract
Embodiments of the present disclosure disclose a security controller SC restoration method. The method provided by the embodiments of the present disclosure 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.
Claims20
A security controller (SC) restoration method, comprising:
- designating, by a master node, a node to which a backup SC belongs, wherein the master node comprises an original domain master (DM) node or a backup DM node;
- sending, by the master node to a first node, a message indicating the backup SC, wherein the message indicating the backup SC comprises an identifier of the node to which the backup SC belongs;
- and
- when 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, on the node to which the backup SC belongs, wherein the message for enabling the SC function comprises the identifier of the node to which the backup SC belongs.
1 more element
A security controller (SC) restoration method, comprising:
- determining, by a node to which a backup SC belongs, that a node to which an original SC belongs is disconnected;
- activating, by the node to which the backup SC belongs, an SC function of the node to which the backup SC belongs, and performing internal authentication;
- receiving, by the node to which the backup SC belongs, a re-authentication request message sent by a second node, wherein the second node is a node except the node to which the backup SC belongs;
- and
- performing, by the node to which the backup SC belongs, authentication on the second node according to the re-authentication request message.
2 more elements
A security controller (SC) restoration method, comprising:
- receiving, by a common node, a message for instructing to enable an SC function that is sent by a master node, wherein the message for instructing to enable the SC function comprises an identifier of a node to which a backup SC belongs, the master node comprises an original domain master (DM) node or a backup DM node, and the common node does not comprises the node to which the backup SC belongs;
- and
- sending, by the common node according to the identifier of the node to which the backup SC belongs, a re-authentication request message to the node to which the backup SC belongs, so that the node to which the backup SC belongs performs authentication on the common node according to the re-authentication request message.
A node, comprising:
- a processor, configured to designate a node to which a backup SC belongs, wherein the node comprises an original domain master (DM) node or a backup DM node;
- and
- a transmitter, configured to send, to a first node, a message indicating the backup SC, wherein the message indicating the backup SC comprises an identifier, transmitted by the processor, of the node to which the backup SC belongs;
- wherein
- the transmitter is further configured to:
- when a node to which an original SC belongs is disconnected, send a message for enabling an SC function to the first node for performing authentication, according to the message for enabling the SC function, on the node to which the backup SC belongs, wherein the message for enabling the SC function comprises the identifier of the node to which the backup SC belongs.
3 more elements
A node, comprising:
- a processor, configured to determine that a node to which an original security controller (SC) belongs is disconnected;
- the processor, configured to activate an SC function of the node when the determining unit determines that the node to which the original SC belongs is disconnected;
- the processor, configured to perform internal authentication after the activating unit activates the SC function;
- and
- a receiver, configured to receive a re-authentication request message sent by a second node, wherein the second node is different from the node;
- wherein
- the processor is further configured to perform authentication on the second node according to the re-authentication request message.
4 more elements
A node, comprising:
- a receiver, configured to receive a message for instructing to enable a security controller (SC) function that is sent by a master node, wherein the message for instructing to enable the SC function comprises an identifier of a node to which a backup SC belongs, and the master node comprises an original domain master (DM) node or a backup DM node;
- and
- a transmitter, configured to send, according to the identifier of the node to which the backup SC belongs, a re-authentication request message to the node to which the backup SC belongs, so that the node to which the backup SC belongs performs authentication on the node according to the re-authentication request message.
