Key Management Problem In WiMAX Technology

Key Management is another problem is WiMax technology, which uses Traffic Encryption Key (TEK) sequence space; it uses sequence number to make different messages. The protocol identifies each Traffic Encryption Key (TEK) with a 2 bit sequence number, enclosing the sequence number from 3 to 0 on every fourth re-key as a problem of replay attack; if replay works, Subscriber Station (SS) could not be able to detect this issue. (D Johnston, J Walker, 2004)
