Key Management Protocol in WIMAX Revisited

Without physical boundaries, a wireless network faces many more vulnerabilities than a wired network does. Compared to Wi-Fi, security has been included in the design of WiMAX systems at the very start. IEEE802.16 standard (WiMAX) provides a security sublayer in the MAC layer to address the privacy issues across the fixed BWA (Broadband Wireless Access). After the launch of this new standard, a number of security issues were reported in several articles. Ever since the beginning, work has been in progress for the neutralization of these identified threats.
