Traceable key block-chain ledger

A system for key tracing, the system comprising:

• one or more processors;
• and
• one or more memory devices in communication with the one or more processors, the memory devices having computer-readable instructions stored thereupon that, when executed by the processors, cause the processors to:
• responsive to detection of an attack on a resource protected by a cryptographic key, retrieve a key block-chain ledger corresponding to the cryptographic key, the key block-chain ledger having one or more transaction blocks, where each transaction block corresponds to a key transaction with the cryptographic key and includes metadata describing the key transaction with the cryptographic key;
• trace the key transactions of the cryptographic key to a point of attack using metadata from the transaction blocks in the key block-chain ledger;
• determine a transaction block corresponding to the point of attack;
• and
• generate an alert indicating the point of attack with metadata from the transaction block corresponding to the point of attack.

A computer storage medium having computer executable instructions stored thereon which, when executed by one or more processors, cause the processors to execute a key trace method comprising:

• responsive to detection of an attack on a resource protected by a cryptographic key, retrieving a key block-chain ledger corresponding to the cryptographic key, the key block-chain ledger having one or more transaction blocks, where each transaction block corresponds to a key transaction with the cryptographic key and includes metadata describing the key transaction with the cryptographic key;
• using metadata from the transaction blocks in the key block-chain ledger to trace the key transactions of the cryptographic key to a point of attack;
• determining a transaction block corresponding to the point of attack;
• and
• generating an alert indicating the point of attack with metadata from the transaction block corresponding to the point of attack.
