Organization of the Thesis. The thesis is organized as follows: Chapter 2 provides the literature study of previous studies had been done relating to the scopes mentioned above and the basic definitions of concepts and methods used in the thesis. Chapter 3 studies the lifeboat accidents.
Organization of the Thesis. In addition to the introduction, there are four other chapters. Chapter 2 describes the security of mobile networks and major terminologies relevant to the contents of the contributions which are made. Related work relevant to mobile network security is investigated in order to assist the conduct of this research. The authentication protocols designed for mobile networks are described. Chapter 3 proposes a secure authentication mechanism for mobile communication systems by integration the proposed of pubic key cryptography and hash chaining function. The new approach proposed is able to remedy the failings of the UMTS. The proposed protocol reduces the network traffic and signalling messages between entities, and consequently the bottleneck at the authentication centre is avoided. It includes the security analysis of the proposed protocol. Chapter 4 includes the efficiency analysis of the proposed protocol and the performance comparison of the proposed scheme with the protocol of UMTS. A fluid mobility model is used to investigate the performance of signalling traffic and load transaction messages between mobile databases such as Home Location Register (HLR) and Visitor Location Register (VLR). Finally, chapter 5 draws conclusions and suggests future work in this research area.
Organization of the Thesis. This thesis consists of six chapters. Chapter One (Introduction) includes background information of the study. Chapter Two (Literature Review) presents an analysis of relevant literature and provides a theoretical base for this study. Chapter Three (Methodology) explains the qualitative research design and methodology used to carry out this study. Also, this chapter explains sampling procedures and instruments which were used to collect the data. The Fourth Chapter (Findings) presents the results of the study. The Fifth Chapter (Discussion) highlights the study’s contribution to knowledge, identified weaknesses and limitations. The final chapter (Conclusion) draws certain conclusions based on the study’s finding and makes recommendation for policy, practice and further research. Chapter Two Literature Review “... xxxxx, whose mother is history, who is the rival of time, depository of deeds, witness of the past, example and lesson to the present, and warning to the future.” Xxxxxx xx Xxxxxxxxx Xxxxxxxx, Xxx Xxxxxxx.
