摘要
A method is provided for generating a public/private key pair and certificate. The method includes providing an integrated circuit (IC) with an IC specific initial public and private key pair and a public key certificate signed by a manufacturer of the IC. A smartcard having stored thereon customer unique configuration data related to the IC is provided to a customer of the IC manufacturer. The smartcard enables the customer to generate a customization value and a customized public key using the customer unique configuration data. In response to the customer receiving the public key certificate signed by the IC manufacturer from the IC, the customer is enabled to provide the customization value, the customized public key, and a public key certificate signed by the customer to the IC. The IC is thus enabled to generate a customized private key, thus providing an IoT device with a public/private key pair and a certificate signed by the device manufacturer without the use of a trusted party.
