Notes on (failed) attempts to instantiate TLR3

Alexander Maximov

, Ericsson (Sweden)

Abstract

In this short paper we share our experience on instantiating the width-extension construct TLR3, based on a variety of tweakable block cipher constructs. As many of our attempts failed, we highlight the complexity of getting a practical tweakable block cipher and the gap between theory and practice.
