Softwarwe optimization of encryption algorithms for LANs

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.

Simulation of Token Ring Lan using petrinet model

Abstract : Since the appearance of computers network until the use of the internet many types of LAN were applied according to the topology or to the way of exchanging the information (access method). To get the better and suitable ways, the need to study the performance of LAN was appeared in order to know the network performance through measuring the time of information receiving, to know which type is suitable for a specific job and place.

FPGA based elliptic curve cryptosystem

Abstract : Elliptic Curve Algorithms (ECA) has been developed to be a desirable algorithm to other public-key cryptosystems such as the Rivest-Shamir- Adleman algorithm (RSA) by offering the smallest key size and the highest strength per bit. It is based on the discrete logarithm in finite field and integer factorization problem. This thesis proposes the design and implementation of cryptosystem used for generation of session key based on elliptic curve. The underlying structures are the standard Galois Fields GF (2m) in standard base representation.

Coding and decoding of telemetry and telecommand in satellite communication using FPGA.

Abstract: Programmable logic devices have replaced application specific integrated circuitsin many Applications due to lower cost, shorter time to market and hardware reconfigurability. Corresponding to this system on a programmable chip design has emerged as a major enabling technology. The implementation of satellite onboard data handling as a system on chip by the use of programmable devices will result in radical improvements and new capability.

Evaluation of multiuser OFDM schemes over home-plug system

Abstract: Since high bit rate for data transmission is required for broadband internet, High Definition TVs (HDTV) and other services, Power-Line Communications (PLC) are a technology that provides a very high-speed digital data transmission using the regular Low Voltage (LV) power lines as the transmission media. With multiple outlets in almost every room, power lines are already the most pervasive network in the home and this will reduce the cost for realization of new telecommunications networks.

Investigation of inner shorted annular microstrip antennas

Abstract: The inner shorted annular microstrip antenna (ISAMSA) is one of the different types of microstrip patches which are widely-used for their numerous advantages. These antennas have the advantage of controlling the radiation pattern by varying the inner and outer radius in the same mode .This thesis presents a study of the design parameters of inner shorted annular microstrip antennas such as the input impedance, the bandwidth, the radiation pattern and the modes that can be excited in this type of antennas using EM-Sight of Microwave Office 2000.

Design of electronic circuits based on parallel genetic algorithms.

Abstract: This study presents an electronic circuit design system based on Genetic Algorithm that uses SPICE to evaluate the circuit performance and compare it to the requirements. A Parallel Genetic Algorithm is used to reduce the running time as the simulator takes very long time to process a circuit. The Genetic Algorithm was implemented using the C++ programming language, to have an efficient and reliable program and to allow the use of low level functionality of the operating system. The implementation was targeted in the Windows operating system.

Design and implementation of telemetry reading of power.

Abstract: With the development of life and the need for more resources (electricity, gas, water and etc.) is increased, some companies began to provide these resources to each household, school, and office. These companies install meters in each consuming place and assign someone to get the reading of that meter. With the increase of buildings, households, offices that use this meter, it’s inappropriate to assign one or even hundred of people to check measured values. To solve these problems, various remote meter reading systems have been proposed.

Bandwidth enhancement of rectangular microstrip patch antenna using multi-slot technique.

Abstract: The microstrip patch in its pure form cannot satisfy the bandwidth requirements for most wireless communication systems. The general philosophy of most of the bandwidth enhancement techniques is to add one or more resonant structures to the microstrip patch configuration. These additional elements may be in the form of slots or other patches. This thesis introduces the design and analysis of bandwidth enhancements for a microstrip patch antenna using different slot configurations.
