B. D. Gonska,A. Schaumann,S. Purrerin the ZK-STARK protocol, we present a practical collision attack on a round-reduced version of . and a preimage attack on some instances of .. To achieve those results, we adapt and generalize several cryptographic techniques to fields of odd characteristic.

A. Capucci,G. Q. Villani,D. Aschieri,A. Rosirate a continuum of progressively less weak keys (from extremely weak keys up to all keys) that can be recovered in substantially less work than previously known. This demonstrates that the imperfection of LEDAcrypt is fundamental to the system’s design.

Simon Topalian,Rady Ho,Georges Kaddissi019) to run the protocol on a cloud computing service, our protocol also compares favorably..Underlying our PSI protocol is a new lightweight multi-point oblivious pesudorandom function (OPRF) protocol based on oblivious transfer (OT) extension. We believe this new protocol may be of independent interest.
