Securing Bandwidth Request Messages in Wimax
Privacy, confidentiality and authentication are the issues which are been focused by the security sub layer which is defined in the IEEE 802.16 standard. WiMAX which is the Wireless Interoperability for Microwave Access is the latest technology for Wireless Communication. It has been developed to replace DSL/fiber cable. It has been developed to provide 'Last mile' broadband connectivity to home or business location. The IEEE 802.16 has many flaws in its security which has led to various vulnerabilities. One of the vulnerability which has been detected by one is the bandwidth request messages. This paper analyses the attacks which can be carried on the bandwidth request messages, its effect on the performance and the suitable solution to counter this attack.
