ABSTRACT:
The present invention relates to an anti-tamper system. The system comprises a circuit pathway having a unique, programmable, evolved chip in the pathway. The chip has logic units with transistors having fixed parameters. The chip has 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. The changes in the route lengths and connections cause the transistors to operate in intermediate analog states. In chip formation, a search and optimization algorithm explores, in a clock-less environment, various route lengths and connections such that the chip can behave in a desired fashion to provide a desired output for a given input. Through use of the evolved chip, the anti-tamper system provides a security benefit of utilizing a unique chip in its pathway.
