摘要
Various embodiments described herein relate to network key manager which is configured to manage keys in nodes in the network, wherein the network key manager including a memory configured to store an update data structure; a processor configured to: determine which nodes are blacklisted; generate the update data structure of volatile private keys for each node that is not blacklisted, wherein the volatile private key is based upon secret information associated with the node and an index, wherein the volatile private key is used for the indexth key update; determine a neighbor node of the network key manager; remove the volatile private key for the neighbor node from the update data structure; encrypt the resulting update data structure and a new network key with the private key for the neighbor node to produce an encrypted message; and send the encrypted message to the neighbor node.
