"Web1 Answer. CCM* as defined by IEEE Std 802.15.4-2011 is a generalization of CCM as defined by RFC 3610. The generalization is that where RFC 3610 allows the tag lengths M {4, 6, 8, 10, 12, 14, 16} which are encoded in a 3-bit field M' where the value 0 is reserved, CCM* also allows the tag length M =0 and encodes it using the value M' =0 in the ...
