Chapter Three Architecture of the security System 3.1 Introduction This chapter is dedicated to present the design considerations and the main implementation steps to establish Zero-Knowledge protocol model, the established proto-type is a web-based application, represented as a web-site. The major requirements (CIA) confidentiality, integrity, and authenticity are covered by the security system. 3.2 Architecture of the security system In order to get a system is characterized by durability, flexibility and resistant any potential change, the security system is designed and consists of three layers: the user interface layer, the application logic layer and the database layer. All these layers in the security system the main goal is to make†¦show more content†¦26 Client Layer WEB BROWSER Control Module ZKP Module Integrity Module Encryption Module Server Layer Messaging Module Tables DB Data Base Layer 26 Figure 3-2 Security system architecture Figure 3-3 present the whole process the client, server will get through and the processed data also. 27 Client Layer Home - Page App. Page Welcome Page Sign-Up Page Log-In Page Main Page Edit Personal Information Personal Messages Page New Page Main Read / Replay Page Main Server Layer Authentication Key exchange Module Integrity Module Encryption / Decryption Module D.B Layer User Table Personal Messages Table Figure 3-3 whole process flow chart 28 Figure 3-4 the functioning of the security system 3.2.1 Client Layer: The users (applicants) can access the data on the server through any web-browser (like Google Chrome or Netscape). To build this system a number of sub-programs were built using some programming languages. The main program was named PhpMyadmin is used to design database. In general the presentation services or the user interface logic is located on the client machine. This layer manages the input/output data and their display. With the intention of offering greater convenience to the user, the system is prototyped on the Internet. The user interface layer contains HTML and PHP components needed to collect incoming information and to display
