Blockchain technology is a core technology in modern deployed payment applications. There has been widespread progress regarding the application of Blockchain in the financial field. Using the blockchain technology in the financial field, resulted in the creation and establishment of multiple applications of Blockchain Wallets based on Blockchain t...

The main drawback of the Bitcoin cryptocurrency is its low scalability, which somehow is a consequence of the Proof-of-Work (PoW) consensus algorithm. So many other cryptocurrencies use the Proof-of-Stake (PoS) algorithm. In this paper, we present an outline of the architectural design of ARAM technology and arrangements built on PoS, ARAM is a sca...

Due to the widespread use of smart phones, location-based services (LBS) has become important in all aspects of human’s life. LBS offer many advantages to the mobile users to retrieve information about their location. Some LBS services use the smartphone’s location and service provider information to offer directions, targeted recommendations, or o...

Homomorphic Cryptography raised as a new solution used in electronic voting systems. In this research, Fully Homomorphic encryption used to design and implement an e-voting system. The purpose of the study is to examine the applicability of Fully Homomorphic encryption in real systems and to evaluate the performance of fully homomorphic encryption...

Due to rapid changes and consequent new threats to computer networks there is a need for the design of systems that enhance network security. These systems make network administrators fully aware of the potential vulnerability of their networks. This paper designs a Network Monitoring System (NMS) which is an active defense and complex network surv...

Voice over Internet Protocol (VoIP) service is growing very fast. Service providers offer VoIP service along with traditional data services using the same IP infrastructure. That is why today it is one of the most dominant technologies for communication. In this paper, simulative investigations have been done for VoIP service in WiFi campus network...

The increasing number of malwares has led to an increase in research work on malware analysis studying the malware behavior. The malware tries to leak sensitive information from infected devices. In this paper, we study a specific attack method, which distributes the data source and the point of data loss on different versions of the malware applic...

Voice over Internet Protocol (VoIP) service is growing very fast and supported by many applications. Its interactive nature makes it very attractive service. VoIP requires a precise level of quality to be utilized. Quality of Service (QoS) is determined by factors like jitter, traffic sent, traffic received and end-to-end delay. In this paper, we s...

Enterprise network (EN) supports thousands of users, and interconnects many networks. EN integrates different operating systems and hosts hundreds of servers that provide several services such as web applications, databases, E-mail, and others. Security threats represent a serious problem to EN. They try to damage enterprise confidentiality, integr...

Many researches were done to find creative techniques, for Android platform, that can detect malware in easy and reliable manner. The aim is not only the effectiveness but to have less processing time, and less resources consumption. This research provide a solution for a part of this problem by finding an easy and fast way to analyze static applic...

This thesis presents a new approach to the visualization of sound for deaf assistance that simultaneously illustrates important dynamic sound properties and the recognized sound icons in an easy readable view. .In order to visualize general sounds efficiently, the MFCC sound features was utilized to represent robust discriminant properties of the s...

Positioning systems can be used for different purposes and for different services, so a lot of research tries to find low error techniques with good results, GPS Global Positioning System is widely used but unfortunately it is difficult to use for indoor applications, WiFi positioning system (WPS) solve this problem, So in this paper we introduce s...

Mobile computing is an important field in information technology, because of the wide use of mobile devises and mobile applications. Clustering gives good results with information retrieval (IR), It aims to automatically put similar applications in one cluster. In this paper, we evaluate clustering techniques in Android applications. We explain how...

In Palestine, 44.7% of the population is under 16 with literacy rate of 91.9% over all of the population. More than half of Palestinian youth own computers and have access to the Internet. With such prospect, ensuring information security and spreading awareness of it is one of the main challenges facing researchers on a national level. In this...

Power consumption is an increasingly pressing problem in modern processor design. Since the on-chip caches usually consume a significant amount of power so power and energy consumption parameters have become one of the most important design constraint. It is one of the most attractive targets for power reduction. This paper presents an approach to...

In this paper, we present a new block replacement policy in which we proposed a new efficient algorithm for combining two important policies Least Recently Used (LRU) and Least Frequently Used (LFU). The implementation of the proposed policy is simple. It requires limited calculations to determine the victim block. We proposed our models to impleme...

Abstract- Failure of addressing all IEEE 802.11i Robust Security Networks (RSNs) vulnerabilities enforces many researchers to revise robust and reliable Wireless Intrusion Detection Techniques (WIDTs).In this paper we propose an algorithm to enhance the performance of the correlation of two WIDTs in detecting MAC spoofing Denial of Service (DoS) at...

A software framework is dedicated to the efficient execution of procedures for supporting the construction of applications. Nowadays Java Application Servers are widely used in software development.
