P802.15.3/D0A Abstract This presentation gives
a summary of the pros and cons for the selection
of the symmetric algorithm portion of the
security suites for 802.15.3 with a focus on
AES. Purpose Provide information to the
802.15.3 working group to allow the group to make
the best decision for symmetric security for
802.15.3. Notice This document has been
prepared to assist the IEEE P802.15. It is
