I was just wondering this. What if IV=0, does it threaten the security in general? —Preceding unsigned comment added by 98.230.18.172 (talk) 18:36, 03:30, 3 December 2008 (UTC)[reply]

Interesting Question. I would say no. 0 is a valid IV. IV have to be non repeating. So an adversary gets no additional information. —Preceding unsigned comment added by 87.185.76.112 (talk) 17:50, 4 February 2011 (UTC)[reply]

IV are separate from 'rounds' and 'keys'. IVs work on the stream. Rounds and Keys on a Block. —Preceding unsigned comment added by 87.185.76.112 (talk) 18:08, 4 February 2011 (UTC)[reply]
