A first server device includes a managed device coupled to a first remote access controller device that receive a device locking key from the key management system and uses it to lock the managed device. The first remote access controller device then encrypts the device locking key, broadcasts the encrypted device locking key through the network to a second remote access controller device in a second server device, and erases the device locking key. Subsequently, the first remote access controller device transmits a request to retrieve the encrypted device locking key. When the first remote access controller receives the encrypted device locking key from the second remote access controller device, it decrypts the encrypted device locking key and uses the resulting device locking key to unlock the managed device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Redundant device locking key management system","description":"A redundant key management system includes a key management system coupled to a plurality of server devices through a network.
