    摘要： A secure electronic structure including a plurality of sub-lithographic conductor features having non-repeating random shapes as a physical unclonable function (PUF) and an integrated circuit including the same are provided. Some of the conductor features of the plurality of conductor features form ohmic electrical contact to a fraction of regularly spaced array of conductors that are located above or beneath the plurality of conductor features having the non-repeating shapes, while other conductor features of the plurality of conductor features do not form ohmic electrical contact with any of the regularly spaced array of conductors. Thus, a unique signature of electrical continuity is provided which can be used as a PUF within an integrated circuit.

    摘要： A secure electronic structure is provided including a via array as a physical unclonable function (PUF). Specifically, the secure electronic structure includes an array of electrical contact vias located between a lower level of a first regularly spaced array of conductors and an upper level of a second regularly spaced array of conductors. Each electrical contact via of the via array is individually addressed through the first regularly spaced array of conductors in the lower level and the second regularly spaced array of conductors in the upper level and has a resistance value. Each resistance value of each electrical contact via forms a distribution of resistance values, wherein the distribution of resistance values is random. This random distribution of the resistance values of the array of electrical contact vias can be used as a physical unclonable function in the electronic structure of the present disclosure.
