Journal of Data Processing Noudjoud Kahya-Abbaci, Nacira Ghoualmi 2 1 2012 http://www.dline.info/jdp/fulltext/v1n1/4.pdf Recently the most accepted standard for wireless broadband access is termed as Wimax which ensures effective and seamless technology. By realizing this value we in this work, propose a new innovative security solution for wireless access in a long range. We have studied in depth the issues in the communication layers and hence we classified these limitations in the protocols. The two identified attacks are man-in-the-middle attacks and denial of service attacks. This classification is effective as it considers un-authentication, unencryption message and unmutual authentication.
