Encryption Problem in Wimax Technology

Encryption Problem:

With the improvements of Wimax (IEEE 802.16e standard), it supports for Advance Encryption Standard (AES) cipher, actively giving strong support for confidentiality of data traffic. Like the Wi-Fi (802.11) specification, management frames are not encrypted, permitting an attacker to collect data about subscribers in the area and other potentially sensitive network characteristics. (Joshua Wright,Dec 12 2006)

I will conduct research and propose the possible encryption technique to make the communication through WiMAX network more secure so that the attacker cannot access the information regarding the user or the service provider. I have to discuss about the management frames and suggest solution for it to give better quality of service.
