Abstract

A method and a system for integrating post quantum cryptographic algorithms into TLS. The method includes transmitting a client hello message to a server including a request for post quantum cryptographic (PQC) mode of operation and a PQC public client key, receiving a server hello message from the server in response to the client hello message including a PQC server key exchange generated from the PQC public client key. The method includes determining the server hello message includes an authorization to operate the PQC mode of operation. The method also includes transmitting a second client hello message to the server including a PQC encrypted client key share. The PQC encrypted client key share is encrypted using a client encryption key. The method includes receiving a second server hello message that includes a PQC encrypted server key share and decrypting the PQC encrypted server key share using a server encryption key.
