Abstract
Exemplary methods, apparatuses, and systems include a central controller receiving a request to generate a new encryption key for a security group to replace a current encryption key for the security group. The security group includes a plurality of hosts that each encrypt and decrypt communications using the current encryption key. In response to receiving the request, the central controller determines that a threshold period following generation of the current encryption key has not expired. In response to determining that the threshold period has not expired, the central controller delays execution of the request until the expiration of the threshold period. In response to the expiration of the threshold period, the central controller executes the request by generating the new encryption key, storing a time of creation of the new encryption key, and transmitting the new encryption key to the plurality of hosts.
