A method of storing data on target data processing devices, the method comprising: for each target data processing device, using a security data processing device on which first data has been stored to: obtain a device cryptographic certificate from the target data processing device, the device cryptographic certificate having been generated by, and being verifiable as having been generated by, a trusted entity; verify the device cryptographic certificate as having been generated by the trusted entity; generate second data using the first data; and store the second data on the target data processing device.

Storing data on target data processing devices

A method of enabling program code stored on target data processing devices, the method comprising: receiving an in encrypted value of a permitted number of target data processing devices that are permitted to have program code stored on them enabled, and using a security data processing device to decrypt the encrypted value and store the decrypted value on the security data processing device; and for each target data processing device, using the security data processing device to: determine whether the value of the permitted number of target data processing devices is greater than zero; if so, obtain a device identifier from the target data processing device; generate a license key from the device identifier; store the license key on the target data processing device; and decrement the value of the permitted number of target data processing devices.
