ABSTRACT:
A key management of cryptographic keys has a data package including one or more cryptographic keys that are transferred to a personal device100from a secure processing point150of a device assembly line in order to store device specific cryptographic keys in the personal device100. In response to the transferred data package, a backup data package is received by the secure processing point150from the personal device100, which backup data package is the data package encrypted with a unique secret chip key stored in a tamper-resistant secret storage125of a chip110included in the personal device100. The secure processing point150is arranged to store the backup data package, together with an associated unique chip identifier read from the personal device100, in a permanent, public database170.
