Abstract
An access gateway may grant a requestor access to a computer resource. The requestor may receive a credential from an identity provider and calculate a zero-knowledge proof of possession of the credential. The requestor may use the proof to request access to the computer resource. The identity provider may record a policy corresponding to the credential in a distributed ledger. The access gateway may, subject to verifying the proof, retrieve the policy from the distributed ledger. The access gateway may grant the requestor access to the computer resource as indicated by the policy. For example, the access gateway may allow the requestor to transfer data from a classified data storage component to a declassified data storage component. In some cases, the classified data storage component may encrypt data (e.g., using an encryption key provided by the requestor and/or the declassified data storage component) prior to transfer.
