A General Construction of Tweakable Block Ciphers and Different Modes of Operations
Debrup Chakraborty and Palash Sarkar
Abstract
This work builds on earlier work by Rogaway at Asiacrypt 2004 on
tweakable block cipher (TBC) and modes of operations. Our first
contribution is to generalize Rogaway's TBC construction by working
over a ring {\ring} and by the use of a masking sequence of
functions. The ring {\ring} can be instantiated as either
Note: Subsequent to the previous version, we realised that word oriented LFSRs can be used to generate the masks.
