[P1619-2] Question: Should we only allow one data unit size within a key scope?
Hi Folks,
One of the questions from the P1619.2 sponsor ballot is as follows:
(Page 4, Subclause 5, line 12): Note that for IEEE Std 1619-2007, all data units within a particular key scope are required to have the same size. The sentence here allows for them to be different sizes. Do we want this? If different sizes are allowed, how does an implementation track each size, and are there security implications with an adversary being potentially able to change these sizes, since there is no authentication in this system?
What are the thoughts from the group?
