A CHAOS-BASED KEYED HASH FUNCTION FOR MOBILE AD HOC WIRELESS APPLICATION : This thesis presents the design of communication in the Mobile Ad hoc Networks (MANET) is challenging due to limited wireless transmission ranges of node mobility, limited power resources, and limited physical security. The advantages of MANET include simple and fast deployment, robustness, adaptive and self organizing networks. Nonetheless, routing protocols are important operations for communication among wireless devices. Assuring secure routing protocols is challenging since MANET wireless networks are highly vulnerable to security attacks. Most traditional routing protocols and message authentication designs do not address security, and are mainly based on a mutual trust relationship among nodes. This paper therefore proposes a new chaos-based keyed hash function that can be used for communication protocols in MANET. The proposed chaotic map realizes an absolute-value nonlinearity, which offers robust chaos over wide parameter spaces, i.e. high degree of randomness through chaoticity measurements using Lyapunov exponent. The proposed keyed hash function structure is compact through the use of a single stage chaos-based topology. Hash function operations involve an initial stage when the chaotic map accepts input message and initial conditions, and a hashing stage where alterable-length hash values are generated iteratively. Hashing performances are evaluated in terms of original message condition changes, statistical analyses, and collision analyses. Re
