WiMAX Networks – architecture and data security

Abstract

This document presents thorough information on the WiMAX technology, itsdetailed architecture and illustrates security mechanisms employed. The first part discusses basic properties and components of WiMAX network. Individual sub-layers of the network operation have been presented. The second part describes all security-related aspects and solutions employed to ensure secure data exchange: cryptographic keys generation and exchange, authentication processes and encrypted data exchange. The last part illustrates potential attacks, means of effective protection and methods for improving security in WiMAXnetworks.
