Abstract
A computer implemented method of a secure computing component to provide access to a cryptographic key, the key being associated with the secure component by a digitally signed record in a blockchain wherein the blockchain is accessible via a network and includes a plurality of records validated by miner computing components, the method including receiving a request from another secure computing component to associate the key with the other component, the request having associated identification information for a requester of the key; responsive to a verification of an entitlement of the requester, generating a new record for storage in the blockchain, the new record associating the key with the other component and being validated by the miner components; and further responsive to the verification, securely transferring the key to the other component so as to provide access to the key to the key requester via the other component.
