Abstract
A spare robot controller for replacing any one of a plurality of initial robot controllers configured to control operation of respective industrial robots includes a key storage storing a plurality of shared keys and a secure storage. The spare robot controller is configured to decrypt, using one of the shared keys, an encrypted backup copy of the initial robot controller to be replaced, and to store resulting data in the secure storage. In embodiments, the is configured to extract data from the secure storage during operation and to encrypt the extracted data, using a selected one of the shared keys, for storage as a backup copy in a backup storage available to all of the initial robot controllers.

A method for providing a spare robot control, which is to replace an initial robot controller configured to control operation of an industrial robot, the method comprising:
- supplying at least a shared key (K10) to the spare robot controller;
- enabling loading of a backup copy ({C}K10) encrypted with the shared key into the spare robot controller;
- and
- causing the spare robot controller to decrypt the loaded backup copy using the shared key and store resulting data (C) in a secure storage of the spare robot controller.
A configurable spare robot controller adapted to replace any one of a plurality of initial robot controllers configured to control operation of respective industrial robots, the spare robot controller comprising:
- a key storage storing a plurality of shared keys (K10, K20, K30;
- and
- a secure storage,
- wherein the spare robot controller is configured to decrypt, using one of the shared keys, an encrypted backup copy ({C}K10, {C}K20, {C}K30) of the initial robot controller to be replaced, and to store resulting data (C) in the secure storage.
