Abstract: A computer system is provided for protecting an original circuit design for an integrated circuit. The computer system includes a logic circuit replacement tool that generates a redacted circuit design for the integrated circuit by replacing logic circuits in the original circuit design with first and second configurable circuits that perform logic functions of the logic circuits when a bitstream stored in storage circuits configures the first and the second configurable circuits. The logic circuit replacement tool couples one of the storage circuits that stores a bit in the bitstream to an input in each of the first and the second configurable circuits in the redacted circuit design.

Abstract: A first semiconductor device includes a processor configured to generate a random number at initial test of a second semiconductor device after fabrication of the second semiconductor device in a supply chain related to the second semiconductor device, and send the generated random number to the second semiconductor device. The processor is further configured to receive a first signature that is signed over the sent random number by the second semiconductor device using a first private key that is stored in the second semiconductor device, among a first private and public key pair, and test the received first signature, using a first public key that is stored in the first semiconductor device, among the first private and public key pair, to determine whether the second semiconductor device is authenticated.
