A Comparison of Security in Wireless Network Standards with a Focus on Bluetooth, WiFi and WiMAX
As wireless networks are finally coming of age, people and organizations start to implement critical applications and infrastructures based on them. As most wireless net-work standards have been designed with security as an afterthought, severe security shortcomings were the results and several improvements and amendments were necessary to fix the worst. Founded on a series of insecure implementations and design faults, recent standards and amendments show some improvements. To cover personal area, local area and wide area wireless networks, the following standards have been chosen as examples: IEEE 802.15.1 Bluetooth, IEEE 802.11 Wi-Fi and IEEE 802.16 WiMAX.
