Abstract
In some examples, a first computing device of a plurality of computing devices may send, to a key management (KM) device, a request for information related to at least one of an active key encryption key (KEK) or a pre-active KEK associated with an entity. The first computing device may receive, from the KM device, an indication that the KM device does not have an active KEK or pre-active KEK. In response, the first computing device may send an instruction to the KM device for creation of a pre-active KEK for the entity. Based on subsequently determining that there are a plurality of pre-active KEKs for the entity available from the KM device, the first computing device may send an instruction to the KM device to activate the pre-active KEK having an earliest creation time, and the first computing device may receive an active KEK for the entity.
