Abstract
A server and a device can support secure sessions with both (i) post-quantum cryptography (PQC) key encapsulation mechanisms (KEM) and (ii) session resumption. In an initial secure session, the device and server can mutually generate a first shared secret key Kfrom a first KEM based on a device PKI key pair. The device and server can mutually generate a second shared secret key Kfrom a second KEM based on a server PKI key pair. The device and server can mutually generate a symmetric ciphering key Sfrom both Kand K. The server can encrypt an identity for a 'pre-shared' secret key (PSK-ID) with S. The device and server can (i) mutually generate a PSK from both Kand Kand (ii) close the initial secure session. The device can transmit a message to resume the session, where the message includes the PSK-ID and a MAC value.
