An integrated circuit is provisioned after the integrated circuit has been sold and integrated into a customer's product. During provisioning, the integrated circuit is booted in a secure manner using a security value, such as a cryptographic key, owned by a manufacturer of the integrated circuit, or by a purchaser of the integrated circuit, to establish a secure communications channel with a provisioning server. Once the secure communications channel is established, the integrated circuit can be provisioned with a security value that is owned by the purchaser of the integrated circuit and the manufacturer's security value is disabled.
