Embodiment Construction
[0044] refer to figure 1 , shows the integrated circuit 1 and the external registration device 2 . The integrated circuit 1 is a fixed logic device (as opposed to a programmable logic device). Thus, integrated circuit 1 includes logic circuits and other blocks whose functionality is fixed at the time of manufacture, but which may be individually selectively enabled or disabled and / or customized after manufacture.
[0045] The integrated circuit 1 comprises a unique code generator 3 for reproducibly generating a code 4 inherently unique to the integrated circuit 1 . Unique Code Generator 3 is based on Physically Unclonable Functions (PUF). The unique code 4 depends on the intrinsic physical properties of the components in the integrated circuit 1 . For example, the unique code generator 3 may generate the unique code 4 using the value at startup of the memory element. Code 4 is unique to integrated circuit 1 even with respect to other integrated circuits (not shown) of the ...
