Abstract:
1. An anti-tamper system, comprising: a circuit pathway having a unique, programmable evolved chip in the pathway; and wherein the evolved chip has logic units with transistors, the transistors having fixed parameters, and the evolved chip having route lengths and connections between the logic units that are formed in an evolutionary formation of the chip such that the evolutionary formation changes the route lengths and connections between the logic units to create feedback and delay changes, with the changes in the route lengths and connections causing the transistors to operate in intermediate analog states, where in formation of the evolved chip, a search and optimization algorithm is used to explore, in a clock-less environment, various route lengths and connections such that the evolved chip can realize a transfer function by producing an output for a given programmed input, whereby through use of the evolved chip, the anti-tamper system provides a security benefit of utilizing a unique chip in its pathway.
