What is WiMAX security 

WiMAX is the much-anticipated broadband wireless access mechanism for delivering high-speed connectivity over long distances, making it attractive to Internet and telecommunications service providers. Designed by the IEEE 802.16 committee, WiMAX was developed after the security failures that plagued early IEEE 802.11 networks.

WiMAX Security includes :

* Authentication : WiMAX authentication relies on PKM-EAP (Extensible Authentication Protocol) and TLS (Transport Layer Security.

* Encryption : WiMAX encryption uses CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol), which uses the AES algorithm for data encryption.

* WiMAX encryption also supports the earlier Triple DES standard.

* Availability :WiMAX deployments will use licensed RF spectrum, giving them some measure of protection from unintentional interference.

* WiMAX Threats :Despite good intentions for WiMAX security, there are several potential attacks open to adversaries, including:
# Rogue Base Stations
# DoS Attacks
# Man-in-the-Middle Attacks
# Network manipulation with spoofed management frames

WiMAX, the Worldwide Interoperability for Microwave Access, is a telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access. It is based on the IEEE 802.16 standard, which is also called WirelessMAN. WiMAX allows a user, for example, to browse the Internet on a laptop computer without physically connecting the laptop to a router, hub or switch via an Ethernet cable. The name WiMAX was created by the WiMAX Forum, which was formed in June 2001 to promote conformance and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL."

WiMAX Security scheme/protocol

Realizing the sticking point that security has been in the widespread adoption of broadband wireless service, the IEEE and the Forum both determined to define a robust security environment. WiMAX security supports two quality encryptions standards, that of the DES3 and AES, which is considered leading edge.

hi seeta WiMAX (Worldwide Interoperability for Microwave Access) is a wireless industry coalition dedicated to the advancement of IEEE 802.16 standards for broadband wireless access (BWA) networks.
According to the WiMAX forum, the group's aim is to promote and certify compatibility and interoperability of devices based on the 802.16 specification, and to develop such devices for the marketplace. WiMAX is expected to provide about 10 megabits per second of upload and download, at a distance of 10 kilometers from a base station.

In May of 2008, Sprint and Clearwire announced that they would be combining their WiMax businesses, creating a new mobile broadband company. Intel, Google, Comcast, Time Warner Cable and Bright House Networks combined to invest $3.2 billion dollars in the venture. The announcement followed years of delays in Sprint's effort to roll out Xohm, a mobile WiMax network in the United States.

Realizing the sticking point that security has been in the widespread adoption of broadband wireless service, the IEEE and the Forum both determined to define a robust security environment. WiMAX security supports two quality encryptions standards, that of the DES3 and AES, which is considered leading edge. The standard defines a dedicated security processor on board the base station for starters. There are also minimum encryption requirements for the traffic and for end to end authentication---the latter of which is adapted from the data-over-cable service interface specification (DOCSIS) BPI+ security protocol.



Basically, all traffic on a WiMAX network must be encrypted using Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP) which uses AES for transmission security and data integrity authentication.



The end-to-end authentication the PKM-EAP (Extensible Authentication Protocol) methodology is used which relies on the TLS standard of public key encryption.

At least one chip company designed processors to support this standard of onboard security processor.
