    A threshold authenticated encryption scheme using hybrid problems

    Full text link
    In this paper, we propose a threshold authenticated encryption scheme using both factoring and discrete logarithm problems.We apply the concept of threshold cryptography in the verification and message recovery phase, where t out of n recipients are required to verify and recover the message. Security analysis shows that our scheme will remain secure even if one of these problems can be solved

    Rivisit grid computing security

    Full text link
    Recent studies have shown that Grid Computing provide computational power, data storage and network bandwidth of under utilized resources at a minimal cost to the end user. It integrates geographically distributed resources and perform collaborative task. Since the goal of grid is resource sharing, computer resource will be accessed by a lot of users from different virtual organizations (YO). The security requirement becomes more vital to the Grids. Securities playa major role in providing the confidentiality of the communication, the integrity of data and the privacy of the user information. This paper focuses on to define current grid security issues and address grid security problem and challenges

    Smart Clinic: Health Smart Card System

    Full text link
    The project focuses on creatinga new smart environment as an alternative to the current conventional health care system sign in and data access. The learning of currenttechnology which is the smart card architecture is determined feasible to react with the difficulty stated as an answer. The current health care systemis considered as inefficient as it consumes time and create annoying atmosphere especially in crowded health center. This could produce danger if there is an unexpected emergency case which requires immediate actions by both the patient and the doctors. The conventional health system requires the patientto fill in forms to be admittedin order to receive treatment and consulted by a doctor. The objective ofthis project is to conducta studyand find a solutionto overcome this problem. Furthermore, the ease of usage for both the patientsand the health systempersonnel must also be met. So, a smart card system implementation is proposedin order to overcome the problem stated and furthermore improve the situationin the currenthealth care system. The project developed can reduce the admission time to a health care center, provide a better patient's information storingand data management coordination embedded with security features ensuringdata safetyand maintains its integrity. In order to develop the solutions proposed, a system engineering process is applied to get determined results. The Incremental Development model is chosen as its compatibility to the vital system discussed and strict processes that ensure the outcome produced is satisfying. Many attempts have been made to computerize the management of patient records usingadvancedcomputing and networking facilities across hospitals, clinics,and other health care center. Therefore, the author hopes that the system is a move towards realizing the smart environment health care system

    A change impact analysis tool for software development phase

    No full text
    Accepting too many software change requests could contribute to expense and delay in project delivery. On the other hand rejecting the changes may increase customer dissatisfaction. Software project management might use a reliable estimation on potential impacted artifacts to decide whether to accept or reject the changes. In software development phase, an assumption that all classes in the class artifact are completely developed is impractical compared to software maintenance phase. This is due to some classes in the class artifact are still under development or partially developed. This paper extends our previous works on developing an impact analysis approach for the software development phase in automating the approach which we call it CIAT (Change Impact Analysis Tool). The significant achievements of the tool are demonstrated through an extensive experimental validation using several case studies. The experimental analysis shows improvement in the accuracy over current impact analysis results

    An insight into internship program for undergraduate Arabic language learners in Malaysia

    Full text link
    This study attempts to investigate the outcome of the internship training program in the Department of Arabic Language and Literature, at the International Islamic University Malaysia (IIUM). Methodologically, this study was conducted to gather the opinions and experience on the internship program among Arabic language and literature students. The participants were purposively selected from 57 out of 66 students who have completed their three months internship program either in the public or private sector from July to September 2015 by using an online survey and open-ended questionnaire. General findings from this study show that internship training has essentially improved their soft skills and increased their workplace literacy and well-being. Despite the poor perception of Arabic language in the mutual graduate employability as well as its practicality aspects and job market by the industry, Arabic language and literature students are well accepted in both private and public sectors to undertake their internship training as reported in this article. In conclusion, internship training is crucial, particularly among Arabic language and literature students as it enriches their experiences, knowledge and skills in both their personal and social life. It also increased their level of confidence to explore their future opportunity in the Malaysian job market including setting up their own businesses through entrepreneurship knowledge and skil
