Method of enrolling a device into a PKI domain for certificate management using factory key provisioning

摘要

A method, mobile device, and PKI are provided for enrolling a mobile device into a PKI domain for certificate management is provided. A first asymmetric key pair and a unique identifier is established in a device. The first asymmetric key pair includes a public key and a private key. The public key and the unique identifier are transferred to the PKI domain. The public key and the unique identifier are imported into the PKI domain. The device generates a second asymmetric kay pair and sends a certificate signing request (CSR) that is protected with the digital signature of the first asymmetric key pair. The CSR is transferred to the PKI domain. The PKI domain authenticates the CSR using the first public key and the unique identifier. Upon validation, the PKI domain issues a certificate to the device.
