Abstract

Proposed is a method of securing a manufactured computing device (1) to be performed by a manufacturer thereof and comprising: a) installing, during manufacture of the computing device, a cryptographic device identity record (2) on the computing device, the cryptographic device identity record (2) comprising at least a private key (21) and a certificate (22) certifying a public key (221) corresponding to the private key; b) generating a certificate revocation secret (3) associated with the issued certificate; and c) causing the certificate revocation secret to be transferred to a customer using a transfer method that keeps it separate from the manufactured computing device (1). Also proposed is a corresponding apparatus; and a kit-of-part-system comprising the computing device and a physical or digital embodiment of the certificate revocation secret. Revocation of a cryptographic device identity record in case of loss of control over the computing device is facilitated.
