    Abstract: A method, in a server, for exchanging cryptographic keys for quantum-secure communication between the server and a client. The method includes: receiving a request message for a secure communication channel from a client, including at least one quantum-secure public ephemeral key and a first secret text; decapsulating the first secret text with a decapsulation function using a quantum-secure secret static key of the server, including generating a first secret; encapsulating the quantum-secure public ephemeral key with an encapsulation function including generating a second secret text and a second shared secret; encapsulating a quantum-secure public static key of the client using the encapsulation function, including generating a third secret text and a third shared secret; generating symmetric keys using at least the first, second, and third secrets; and sending a response message to the client, including the second and third secret texts.
