| description | The invention provides a computer intercluster key management method and system. The method includes that a first cluster master node security agent sends a key agreement request message including a key seed to a second cluster master node security agent, and the second cluster master node security agent is enabled to send a key agreement response message to the first cluster master node security agent and synchronizes the key seed to second cluster slave nodes, and the key seed is used for generating a key; the key seed is synchronized to first cluster slave nodes; when the key seed is judged to be successfully synchronized to the first cluster slave nodes and the second cluster slave nodes, the key seed state of a first cluster master node is set as a state waiting to be enabled; when the second cluster master node security agent judges that the seed key is synchronized to the second cluster slave nodes and the first cluster slave nodes successfully, the key seed state of a second cluster master node is set as a state waiting to be enabled. Intercluster key synchronization and key pre-enabling schemes are provided, and random increase and decrease of cluster devices is supported. |
