AEZ v5

[Phillip Rogaway]

Dear Colleagues,

In response to the bug in AEZ v4 announced by Gaëtan Leurent
on this mailing list (12 March 2017), please find attached
an updated version of the AEZ spec, as well as updated
software.

The change made was to simplify the tweakable blockcipher "E"
(lines 400-405 of the pseudocode on p.7). An explanation for
the change is given at the bottom of p.9 and in the change-log
on p.21.

The same material as what's attached is available at the
AEZ homepage, http://web.cs.ucdavis.edu/~rogaway/aez/

Thanks again to Xavier Bonnetain, Patrick Derbez,
Sébastien Duval, Jérémy Jean, Gaëtan Leurent, Brice Minaud
and Valentin Suder.
