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 genesis block for a key block-chain ledger corresponding to the cryptographic key, and securely modifying the genesis 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 corresponding to the first key transaction with the cryptographic key and adding the first transaction block to the key block-chain ledger, and securely modifying the first transaction block to include metadata describing the first key transaction with the cryptographic key.
