The IEEE 802.16 standard, commonly known as WiMAX, is the latest technology that has promised to offer broadband wireless access over long distance. Since 2001, WiMAX has evolved from 802.16 to 802.16d standard for fixed wireless access and to the new IEEE 802.16e (Mobile WiMAX) standard with mobility support. Meanwhile, its security is becoming a critical issue with the proliferation of wireless threats. Though incorporating some security methods, IEEE 802.16e is still vulnerable to malicious attacks. In this paper, the authors analyze the security of Mobile WiMAX, point out several potential security threats and vulnerabilities. They propose some possible security improvements and solutions to eliminate the vulnerabilities.
