Figure 5.4 shows an example of the revocation operation. Consider a revocated
MN
4
with a first-attached MAG as MAG
3
. ree main messages are transmitted
after revocation. First, the LMA changes the MAG
3
identity to MAG
03
and broad-
casts the new identity to all MNs in the domain. e second message is transmitted
from the LMA to all MAGs, and it includes the new evaluated polynomial with the
new identity, F(ID
MAG03
,x,y,z), along with the MNs that share the MAG
3
as their
first-attached MAG. In Figure 5.4, MN
2
, MN
5
, and MN
10
are those intended nodes
that share MAG
3
as their first attached ...
