This chapter introduces lightweight security protocols based on Physically Unclonable Functions (PUFs). These protocols are specifically designed for mutual authentication and secure message exchange in resource-constrained environments. The chapter discusses various protocols, including the Advanced PUF Protocol, which offers resilience against modeling attacks and exhaustive challenge collection. Additionally, it explores different challenge-response mechanisms that enhance security without increasing computational overhead. Detailed implementation insights, including FPGA-based systems, are provided to demonstrate how lightweight PUF-based protocols can be deployed in IoT devices and other resource-limited systems to achieve robust security.

This chapter introduces lightweight security protocols based on Physically Unclonable Functions (PUFs). These protocols are specifically designed for mutual authentication and secure message exchange in resource-constrained environments. The chapter discusses various protocols, including the Advanced PUF Protocol, which offers resilience against modeling attacks and exhaustive challenge collection. Additionally, it explores different challenge-response mechanisms that enhance security without increasing computational overhead. Detailed implementation insights, including FPGA-based systems, are provided to demonstrate how lightweight PUF-based protocols can be deployed in IoT devices and other resource-limited systems to achieve robust security.
