Abstract

This work focuses on the use of an agile software development methodology namely Dynamic System Development Method (DSDM) for the design and implementation of a general cryptanalysis platform for pedagogical purposes. The project is achieved by several graduate (mainly M.Sc.) student’s successive projects. Indeed, a small pilot project related to the cryptanalysis of classical ciphers is being explored. In this current version of the classical cipher cryptanalysis, only two techniques have been considered, which are brute force attack and letter frequency attack. Besides the educational benefits of expecting the information security side, as well as the other benefits of practicing with certain software development will also be investigated. Thus, the work can be considered to be under the general title of ethical hacking.

Abstract

Poor voice quality in Voice over Internet Protocol (VoIP) models during communication is a common occurrence that VoIP users experience, and can be frustrating when users cannot communicate efficiently. Most people find it difficult when they make calls and there is an echo. In addition time, effort and energy are wasted without any compensation. Users are also frustrated by not receiving, not transmitting or misunderstanding voice messages correctly. This study aims to reduce the threat of bad calls and improve the quality of voice calls. The work is designed to solve the need of the community of users by helping them to reduce communication costs and at the same time enabling them to communicate with greater clarity of signal using a unified communication system such as phones, computers, and tablets with one another. However, when the service requirement is greater than or equal to the threshold, it is segmented into less than or equal to the threshold value in smaller packets with a maximum service requirement. Besides this, if this node is vacant or has a single packet in the service unit, a packet is not saved at an intermediate node. These findings show the validity of hybrid switching that includes three fundamental computer network switching methods: packet, signal, and circuit switching. The results show that the maximum value of the limit is always available, which minimizes the network delay for nearly all traffic concentrations.

Abstract

A new approach for reconfiguring the dual-mode bandpass filter based on multilayer structure is presented in this paper. The primary objective of the proposed work is to reconfigure the dual-mode bandpass filter by tuning both degenerative odd and even mode resonant frequencies. A slow wave resonator with a feed on top layer and a rectangular perturbation patch on second layer are incorporated to design the dual–mode bandpass filter. Two degenerative modes, odd and even modes are excited with cross talk region of the filter. A simple lumped element circuit model for cross talk region is proposed in this work. Both odd and even mode resonant frequencies are tuned by changing the characteristic impedance of both resonator and patch through periodic vias in crosstalk region. The proposed approach for reconfiguring the dual-mode filter is completely different from conventional approach, where only even mode frequency was tuned while keeping odd mode frequency fixed.

Abstract

Microstrip patch antennas are used in various applications due to their low-profile structures. The microstrip patch antennas are widely used in commercial, military, industrial, medical and aerospace applications. Normally, microstrip patch antennas are combined with electronic components and integrated circuits. In this paper, microstrip patch antenna is designed using Rogers RT Duroid 5880 as a dielectric substrate, which has low loss tangent with relative permittivity of 2.2, and overall geometric dimensions of 80 x 78 x 0.787 mm³ . The proposed, microstrip patch antenna is designed and analyzed with CST Microwave studio suite, 2019.The proposed microstrip antenna performs well in simulation, and provides better results. The proposed configuration can be used for ISM band WLAN applications.
