New smooth projective hash functions and one-round authenticated key exchange
Abstract Password-Authenticated Key Exchange (PAKE) has received deep attention in the
last few years, with a recent improvement by Katz-Vaikuntanathan, and their one-round
protocols: the two players just have to send simultaneous flows to each other, that depend
on their own passwords only, to agree on a shared high entropy secret key. To this aim, they
followed the Gennaro-Lindell approach, with a new kind of Smooth-Projective Hash
Functions (SPHF). They came up with the first concrete one-round PAKE, secure in the …
