CS642 Introduction to Information Security
In this project, we are implementing an online poker game. In this design document, we will present our method and protocol so as to ensure the security of the game. The poker game we are implementing is the Texas Hold’em. The appendix lists the rules about how to play it. The rest of this document is the detailed description of the design for this project.
2. Entity Description
There are two types of entities, player and house, in our poker game. The following section describes their roles and actions in this game design.
3. Message Flow
In this section, we describe the communication required and the information involved between players and the house. Figure 1 shows the flow of the game from a player’s point of view. Our message flow is divided into the corresponding sections, which include authentication, money operation, game play, and leave.

4. Architecture Diagram
Figure 2 shows the structure of our poker project. In this section, the functionalities and interfaces among these sub-blocks are described.

Because this is the only entity which interacts with users, it should provide good user interface to allow users to communicate with the House for the poker game. The followings are the user interfaces which should be provided. All the interfaces are temporary and they only provide the idea of what functions and interactions needed. Note that the interface is temporary and subject to change.

6. Design Implementation
In this project, we use C++ with OpenSSL 0.9.7d to construct secure connection, Xerces C++ Library to parse the message to the XML format, and we use FLTK-1.1.4 and OpenGL to build up the user interface.
