Abstract
The IEEE 802.16 is the basis for Worldwide Interoperability for Microwave Access (WiMAX)
certification which is the next evolution in wireless technology. The latest version of the
standard, IEEE 802.16e addresses mobility and also enhances the security sub-layer of the IEEE
802.16 standard. However, security schemes in the standard are utilized and applied only to normal
data traffic after the initial network entry process not to the control messages during the initial
network entry. Security is a key challenge of WiMAX networks and it represents an important example
of such scenarios where capturing and forging packets is relatively easy especially for
unauthenticated and unencrypted messages
during the initial network entry of both WiMAX modes: Point to Multi- Point (PMP), and Mesh.
Therefore, the thesis proposes an innovative hybrid approach to resolve such vulnerability problem
and establishes secret communication channels via insecure domains.
The proposed protocol is based on Bio Cryptosystem to improve current security level of
authentication and Key Exchange between the Subscriber Station (SS), and the Base Station (BS).
Novel proposed protocols are defined as the integration of Advanced Encryption Standard (AES) and
Biometric Digital Key (BDK). The first is concerned with WiMAX PMP mode, to enhance the security
issues in initial network entry mainly the Ranging Request and Response (RNG_REQ/RSP) messages. The
second one is concerned about the WiMAX Mesh mode, to enhance security issues in the initial
network entry mainly the Mesh Network Entry (MSH_NENT), in addition to solve the issue of the
privacy between two nodes that the Mesh network faced. We derived a model of the protocols and
implemented it using MATLAB and CASIA V.5 Database. Finally, the research proposed a permutation
module using fuzzy scheme for biometric template protection.
