Abstract
Techniques are shown for key tracing using a traceable key block-chain ledger involving, in response to detection of an attack on a resource protected by a cryptographic key, retrieving a key block-chain ledger corresponding to the cryptographic key having one or more transaction blocks. Each transaction block corresponds to a key transaction with the cryptographic key and includes metadata describing the key transaction with the cryptographic key. Metadata from the transaction blocks in the key block-chain ledger is used to trace the key transactions of the cryptographic key to a point of attack. A transaction block corresponding to the point of attack is determined and an alert is generated indicating the point of attack with metadata from the transaction block corresponding to the point of attack.
