WiMAX means Worldwide interoperability for Microwave Access. It is the wireless technology and enhancement of 802.16 standards. WiMAX has many salient advantages such as: high data rates, quality of service, scalability, security and mobility. Many sophisticated authentication and encryption techniques have been embedded into WiMAX but it still exposes to various attacks. In WiMAX, security is the major issue for transmission of data from end-to-end. The authors discuss the WiMAX security mechanisms for authentication, encryption and availability. Security protocols are essential for secure transmission of data.
