Zusammenfassung:	Aspects relate to a method, a computer storage medium and a system. The method comprises detecting an attack on data or a system protected by a key, wherein the key has a key block-chain ledger. The method further comprises tracing blocks of the key block-chain ledger to a genesis block of the key block-chain ledger using metadata of transaction blocks of the key block-chain ledger. The method further comprises determining, using the metadata from the block-chain ledger, a transaction block corresponding to a point of attack on the key block-chain ledger or a transaction block relating to the last point at which the key was valid. The method further comprises generating an alert indicating the point of attack or the last point at which the key was last valid.
