PAKEs, oPRFs, algebra with George Tankersley

Security Cryptography Whatever

A conversation that started with PAKEs (password-authenticated key exchanges) and touched on some cool math things: PRFs, finite fields, elliptic curve groups, anonymity protocols, hashing to curve groups, prime order groups, and more.
With special guest, George Tankersley!
