Abstract
A device such as a network-attachable data transfer device may be configured to operate in a cluster to coordinate the storage of data. A cluster manifest may include data and/or metadata related to devices of the cluster. In some cases, a cluster manifest may include, for each of one or more devices of a cluster: an encrypted payload; an identifier associated with the particular device; and an encrypted data entry. The encrypted payload may encode a cryptographic payload key used in part to perform storage operations. The encrypted data entry may include one or more encrypted partitions that are each decryptable by a different security module of the device. The decrypted partitions may be assembled to form a cryptographic key that may decrypt the encrypted payload. The cluster manifest may be provided to a locked device of a cluster as part of a process for unlocking the locked device.
