ePrint Report: Semidirect Product Key Exchange: the State of Play

Christopher Battarbee, Delaram Kahrobaei, Siamak F. Shahandashti

Of the many families of cryptographic schemes proposed to be post-quantum, a relatively unexplored set of examples comes from group-based cryptography. One of the more central schemes from this area is the so-called Semidirect Product Key Exchange (SDPKE), a generalisation of Diffie-Hellman Key Exchange that is plausibly post-quantum. In this report we survey the state of the literature relating to SDPKE, providing a …
