Abstract
A method of post-manufacture generation of the device certificatefor verifying an electronic deviceaccording to a public key infrastructure is provided. The method comprises obtaining, at a certificate generating apparatus, a first keyassociated with the device. A second keyfor the electronic device is derived from the first key. The device certificatefor the PKI is generated with the second key acting as the public keyassociated with the device certificate. In a corresponding way a private keyfor the PKI can be generated by the electronic devicebased on a shared first key. This approach enables the manufacturing cost for manufacturing an electronic device to be reduced whilst still enabling use of a PKI for attesting to properties of the device
