Masked Iterate-Fork-Iterate: A new Design Paradigm for Tweakable Expanding Pseudorandom Function
Abstract
Many modes of operations for block ciphers or tweakable block ciphers do not require invertibility from their underlying primitive. In this work, we study fixed-length Tweakable Pseudorandom Function (TPRF) with large domain extension, a novel primitive that can bring high security and significant performance optimizations in symmetric schemes, such as (authenticated) encryption.
Our first contribution is to introduce a new design paradigm, derived from the Iterate-Fork-Iterate construction, in order to build
