Abstract
Techniques are shown for key management using a traceable key block-chain ledger involving creating a cryptographic key at a key source, generating a key block on a block-chain ledger corresponding to the cryptographic key, and securely modifying the key block to include metadata describing the key source. The techniques also involve performing a first key transaction with the cryptographic key, generating a first transaction block on the block-chain ledger corresponding to the first key transaction with the cryptographic key, linking the first transaction block to the key block and securely modifying the first transaction block to include metadata describing the first key transaction with the cryptographic key.
