16.4.2 PKI Architecture with PUF-Based Key Distribution and LWE

The PUF-based key pair generation scheme with LWE cryptography, as presented in the previous section, can be integrated into a PKI securing a network of 𝑖 clients. Figure 7 shows two client devices communicating directly, either by exchanging secret keys through KEM or DSA. The client devices independently generate Seed 𝑎(i), while the PUFs and their images generate vectors 𝑠1(i) and 𝑠2(i). T...
