In the timeline of wireless domain, Wi-Fi, Bluetooth, zigbee etc are some of the standards, which are being used in today’s wireless medium. In addition, the WiMax is introduced by IEEE in IEEE 802.16 for long distance communication, specifically 802.16e standard for mobile WiMax. It is an acronym of Worldwide Interoperability for Microwave Access. It is to be deliver wireless transmission with high quality of service in a secured environment. Since, security becomes dominant design aspect of every communication, a new technique has been proposed in wireless environment. Privacy across the network and access control management is the goal in the predominant aspects in the WiMax protocol. Especially, MAC sub layer should be evaluated in the security architecture. It has been proposed on cryptography algorithm AES that require high cost. Under this scenario, we present the optimized AES 128 bit counter mode security algorithm for MAC layer of 802.16e standards. To design a efficient MAC layer, we adopt the modification of security layers data handling process. As per the efficient design strategy, the power and speed are the dominant factors in mobile device. Since we concentrate mobile WiMax, efficient design is needed for MAC Security layer. Our proposed model incorporates the modification of AES algorithm. The design has been implemented in Xilinx virtex5 device and power has been analyzed using XPower analyzer. This proposed system consumes 41% less power compare to existing system.展开更多

A, the Asia-Pacific geo-economic map witnesses a double competitive pattern. B, geo-security space shows a Sino-U.S. competitive and low-cooperative trend. C, geopolitical environment highlights the development model competition. D, the high-tech becomes the new driving force for the Asia-Pacific geo-environment changes. The domestic and overseas concerns with the status and prospects of the Asia-Pacific geo-environment focus on a debates between a resistant and confrontational architecture and a competitive cooperation trend. The author believes that the conditions for the resistant and confrontational pattern are no longer in existence and the regional pattern should be promoted in a direction of competitive cooperation.展开更多
