摘要
A network and a device can support a secure session with both (i) multiple post-quantum cryptography (PQC) key encapsulation mechanisms (KEM) and (ii) forward secrecy. The network can operate (i) a first server for conducting KEM with the device and (ii) a second server for generating a digital signature which can be verified by the device with a server certificate. The first server can receive a device ephemeral public key (ePK.device) and generate (i) a server ephemeral public key (ePK.server) and private key. The first server can send, to the second server, data comprising ciphertext for the ePK.device, ePK.server and the server certificate. The second server can (i) generate the digital signature over the data, and (ii) send the digital signature to the first server. The first server can conduct a KEM with ePK.device and the ciphertext in order to encrypt at least ePK.server and the digital signature.
