Redes 802.16: considerações sobre a segurança no modo mesh

Abstract

The standard IEEE 802.16 is now starting to be deployed in large scale all over the world. Within its operational modes, the mesh shows up as one of the most promising in terms of deployment costs and deployment speed. However, as it is a wireless technology, and, consequently, does not have physical boundaries, the standard IEEE 802.16 faces much more vulnerabilities than a wired network does. This paper explains how the mesh mode and the security sublayer of 802.16 networks work and describes the possible attacks on this operational mode.
