A method for assigning addresses to nodes of a bus system, and installation, bus nodes being furnished with an identical delivery address, where (i) an assigning entity, particularly a central computer, start-up computer or bus node sends information to the delivery address via the bus system, (ii) the information includes a first address, (iii) an action is performed whose effect is detected by a first bus node, (iv) the first bus node accepts the first address, (v) the first bus node sends a response to the assigning entity, and (vi) steps (i) through (v) are repeated, each time with a further address for a further bus node.

Disclosed are implementation for revoking and updating a compromised root-of-trust (ROT), including a method comprising determining whether a current validation value, representative of an expected value resulting from application of a validation function to a current certificate, is to be replaced, with the current validation value being stored in a write-restricted non-volatile memory unit of the device. The method also comprises determining at boot time whether a physical presence indicator, configured to be non-actuatable from non-proximate locations, is set to a value indicating that an actuation mechanism (for actuating the physical presence indicator so as to cause content change for the write-restricted memory), has established physical presence with the device, and providing a new validation value in response to determining that the current validation value is to be replaced and that the physical presence indicator indicates that physical presence has been established.
