Claim 24:
25. A non-transitory computer-readable medium having contents which cause a first electronic circuit of a system to perform a method, the method comprising:
receiving, by the first electronic circuit from a second electronic circuit, a request to generate a first digital signature, the request identifying code executable by the first electronic circuit;
executing the code, the executing influencing digital states of all or part of a plurality of electric nodes of the first electronic circuit, the electric nodes being distributed within the first electronic circuit according to a topography; and
generating the first digital signature, in parallel with the execution of the code by the first electronic circuit, the generating including combining digital states of the plurality of nodes of the first electronic circuit, the first digital signature to be compared with a second digital signature generated by a second electronic circuit of the system, the second digital signature being generated based on digital states of a plurality of electric nodes distributed according to the topography within the second electronic circuit.
