The passwords that we use in our everyday life are often chosen to be easily memorable which makes them vulnerable to attacks. This problem is addressed by password-authenticated key exchange (PAKE). The general idea is to enable two parties who share the same (potentially weak) password to establish a strong session key. Most PAKE protocols used today are based on Diffie-Hellman key exchange in prime order groups, hence they are not secure against quantum attackers. A promising candidate for replacing Diffie-Hellman key exchange in a post-quantum world is the Commutative-Supersingular-Isogeny-Diffie-Hellman (CSIDH) key exchange. In this talk, we introduce two novel PAKE protocols based on CSIDH.
