Paper Title: Eliminating the Risk of Malicious Counterfeit Chiplet Components

Paper Abstract: Heterogeneous chiplets are clearly here to stay, but they do introduce serious security issues. Malicious counterfeit silicon can sneak into the manufacturing flow of any chiplet. The best way to validate chiplet authenticity is by using cryptographic techniques such as challenge/response authentication. It relies on a verifier issuing a challenge (e.g., a random number) to the prover, which then calculates a cryptographic response involving the challenge and a pre-shared secret. The prover can thus securely and reliably demonstrate to the verifier that the component is authentic. Such tamper-resistant advanced approaches insure integrity of the overall SiP and can counter the efforts of a determined adversary.
