In this work, we study several post-quantum authenticated key exchange protocols in the setting of supersingular isogenies. Leveraging the design of the well-studied schemes by Krawczyk (2003) , Boyd et al. (2008 ), Fujioka et al. (2013) , Krawczyk and Wee (2015), and others, we show how to use the Supersingular Isogeny Diffie-Hellman (SIDH) and Supersingular Isogeny Key Encapsulation (SIKE) protocols as basic building blocks to construct efficient and flexible authenticated key exchange
