This paper proposes novel robust and low-overhead physical unclonable function (PUF) authentication and key exchange protocols that are resilient against reverse-engineering attacks. The protocols are executed between a party with access to a physical PUF (prover) and a trusted party who has access to the PUF compact model (verifier). The proposed protocols do not follow the classic paradigm of exposing the full PUF responses or a transformation of them. Instead, random subsets of the PUF response strings are sent to the verifier so the exact position of the subset is obfuscated for the third-party channel observers. Authentication of the responses at the verifier side is done by matching the substring to the available full response string; the index of the matching point is the actual obfuscated secret (or key) and not the response substring itself. We perform a thorough analysis of resiliency of the protocols against various adversarial acts, including machine learning and statistical attacks. The attack analysis guides us in tuning the parameters of the protocol for an efficient and secure implementation. The low overhead and practicality of the protocols are evaluated and confirmed by hardware implementation.INDEX TERMS Physical unclonable functions, hardware security, security protocols.

Intellectual property (IP) core reuse is essential for the design process of system-on-chip (SoC). Network-onchip (NoC) has been used as an independent IP core during SoC design. However, the NoC has not been protected via IP protection and paid attention on its innovations. This paper proposes the first known approach to protect the authorship and the usage legitimacy of NoCs using specially designed routing, square spiral routing. The special routing algorithm exploits routing redundancy inherent in the mesh NoCs and transports packets along the paths, which have very low probability to be taken under commonly used routing algorithms. These unique and diverse paths are exploited in this paper to embed information of the author and identify the legal buyer of NoCs, showing high robustness and credibility. The hardware implementation of an IP-protected mesh NoC shows that the area overhead is small, which is ∼0.74%, and the power overhead is ∼0.52%, while the functionality and performance of the network is not affected. In this paper, the approach is presented for the mesh NoC, but the idea is equally applicable to other NoC topologies where the unique and diverse paths also inherently exist.Index Terms-Digital watermarks, intellectual property (IP) protection, network-on-chip (NoC), routing algorithm.

Abstract-We introduce Slender PUF protocol, an efficient and secure method to authenticate the responses generated from a Strong Physical Unclonable Function (PUF). The new method is lightweight, and suitable for energy constrained platforms such as ultra-low power embedded systems for use in identification and authentication applications. The proposed protocol does not follow the classic paradigm of exposing the full PUF responses (or a transformation of the full string of responses) on the communication channel. Instead, random subsets of the responses are revealed and sent for authentication. The response patterns are used for authenticating the prover device with a very high probability. We perform a thorough analysis of the method's resiliency to various attacks which guides adjustment of our protocol parameters for an efficient and secure implementation. We demonstrate that Slender PUF protocol, if carefully designed, will be resilient against all known machine learning attacks. In addition, it has the great advantage of an inbuilt PUF error tolerance. Thus, Slender PUF protocol is lightweight and does not require costly additional error correction, fuzzy extractors, and hash modules suggested in most previously known PUF-based robust authentication techniques. The low overhead and practicality of the protocol are confirmed by a set of hardware implementation and evaluations.
