Abstract
Presented herein are methodologies for establishing secure communications in a post-quantum computer context. The methodology includes receiving, from a first communications device, at a second communications device, a secret seed value, or otherwise obtaining the secret seed value; initializing a session key service with the secret seed value; receiving, from the first communications device, at the second communications device, a pre-shared key identifier; querying the session key service for a pre-shared key corresponding the pre-shared key identifier; receiving, from the session key service, the pre-shared key; deriving a session key based, at least in part, on the pre-shared key; receiving from the first communications device, at the second communications device, data encrypted with the session key; and decrypting the data at the second communications device using the session key.
