Jacqueline Brendel presents paper “PRF-ODH: Relations, Instantiations, and Impossibility Results“ at CRYPTO

CRYPTO is one of the three flagship conferences of the IACR (International Association for Cryptographic Research). As in all the years before, the 37th edition of CRYPTO was held at the campus of the University of California, Santa Barbara (UCSB) in 2017 too. CRYPTO covers all aspects of cryptology in his academic program and undoubtedly, it is the highest ranking conference in the area of cryptography. This year it had as co-located event the 30th IEEE Computer Security Foundation Symposium (CSF).

Jacqueline Brendel successfully presented the paper “PRF-ODH: Relations, Instantiations, and Impossibility Results“ which is a joint work with Marc Fischlin, Felix Günther, and Christian Janson. In this paper they therefore present a systematic study of the different pseudorandom-function oracle-Diffie-Hellman (PRF-ODH) variants in the literature.

In particular, analyzing their strengths relative to each other and carving out that the variants form a hierarchy is part of their work as well as investigating the boundaries between instantiating the assumptions in the standard model and the random oracle model.
