Abstract (en)
[origin: WO2007003341A1] Disclosed is a method for the forgery-proof identification of individual electronic subassemblies. According to said method, the changes in the status of certain storage locations of a memory (2) of an individual electronic subassembly (1) resulting from a specific breakdown of one or several auxiliary functions of said memory (2) are determined, and said changes in status are compared to predetermined memory-characteristic reference changes in the status of specific storage locations of the memory (2) regarding the identity thereof, said reference changes resulting from the specific breakdown of the auxiliary function of the memory (2) of the electronic subassembly (1).
