Summary: | A method of producing a secure integrated circuit (IC), including: loading the IC with a unique identification number (UID); loading the IC with a key derivation data (KDD) that is based upon a secret value K and the UID; producing a secure application configured with a manufacturer configuration parameter (MCP) and the secret value K and configured to receive the UID from the IC; producing a manufacturer diversification parameter (MDP) based upon the MCP and the secret value K and loading the MDP into the IC; wherein secure IC is configured to calculate a device specific key (DSK) based upon the received MDP and the KDD, and wherein the secure application calculates the DSK based upon the MCP, K, and the received UID. |
