From 64470f1b8510699dc357a44004dc924bc139c917 Mon Sep 17 00:00:00 2001 From: Rik Snel Date: Sun, 26 Nov 2006 09:43:10 +1100 Subject: [CRYPTO] lrw: Liskov Rivest Wagner, a tweakable narrow block cipher mode Main module, this implements the Liskov Rivest Wagner block cipher mode in the new blockcipher API. The implementation is based on ecb.c. The LRW-32-AES specification I used can be found at: http://grouper.ieee.org/groups/1619/email/pdf00017.pdf It implements the optimization specified as optional in the specification, and in addition it uses optimized multiplication routines from gf128mul.c. Since gf128mul.[ch] is not tested on bigendian, this cipher mode may currently fail badly on bigendian machines.
