Abstract
A method securely erasing data on a storage drive includes transmitting a communication that initiates an erasure operation on a storage drive and receiving a drive erasure attestation generated in association with erasure operation and by a root-of-trust of the storage drive. The drive erasure attestation includes a first claim that contains cryptographic evidence of a measured state of the storage drive following the erasure operation. The method further includes verifying the first claim and instructing a ledger service to record the drive erasure attestation in a ledger in response to the verification. Verification of the first claim depends upon confirmation of a match between first measurement values in the first claim and a first set of stored values previously-verified as corresponding to a correct implementation of the erasure operation.
