Abstract : Wireless Local Area Network abbreviated as (WLAN) is the new generation of Local Area Networks (LANs) that is to satisfy the mobility and flexibility needed by recent users (mostly laptop users). This thesis presents the theory of IEEE 802.11 standards of WLAN, and discusses various WLAN performance parameters and their configuration. Simulation projects for different WLAN topologies have been built using OPNET network simulator.

Abstract : Smart cards have experienced tremendous growth in the past few years. These small, colorful plastic cards with their semiconductor chips continue to spread throughout the world. Smart card technology can enable an organization to become more secure, efficient, and interoperable while delivering strong authentication, security, identity management, data management, customer support, and communications.

Abstract : Most encryption algorithms are designed without regard to their performance on top-of-the-line microprocessors. The purpose of this thesis is to discuss the software optimization techniques and how they should be applied in the design of encryption algorithms. General software optimization principles are presented that apply to almost all modern CPUs.
