Abstract
A system includes processor(s) and at least one memory communicatively coupled to the processor(s). The processor(s) is/are configured to encrypt at least one set of asset encryption key parts into at least one set of encrypted asset encryption key parts using at least one symmetric key or at least one public key, each public key belonging to a corresponding one of at least one public/private keypair. At least a subset of the at least one set of asset encryption key parts are used to reconstruct the asset encryption key, which is used to perform an action using at least one asset key. The processor(s) is/are also configured to encrypt the encrypted asset encryption key parts and corresponding metadata using a public key of a public/private keypair so the at least one set of encrypted asset encryption key parts is doubly-encrypted.
