Abstract

Techniques are shown for key management using a traceable key blockchain. A first block corresponding to a cryptographic key is generated on the blockchain, and the first block is securely modified to include metadata describing a key source for the cryptographic key. A second block corresponding to a first key transaction with the cryptographic key is generated on the blockchain, the second block is linked to the first block, and the second block is securely modified to include metadata describing the first key transaction with the cryptographic key.
