Cross-Platform Android App Gateway Payment System using Xamarin

Most mobile applications lacks cross platforms portability and capabilities. As such, developers tend to use specific code base that runs only on a native android application built using Java or a native iOS application built using Swift.  In developing mobile application, same application is therefore required to be developed using the appropriate native app required software development. This leads to duplication of efforts, more cost, time consumption and maintenance. Although, the applications are the same, mobile application has to be developed separately because of platform independence. This paper proposes the use of Xamarin in developing mobile apps due to its cross-platform capabilities. Using Xamarin save cost, create a single code base for faster development and less maintenance while still maintaining native app performance and user experience.  To substantiate Xamarin suitability, a gateway payment system was development and tested, the results showed actual cross platform functionalities in a seamless manner

Multi-layer Perceptron Model for Mitigating Distributed Denial of Service Flood Attack in Internet Kiosk Based Electronic Voting

Distributed Denial-of-Service (DDoS) flood attack targeting an Internet Kiosk voting environment can deprive voters from casting their ballots in a timely manner. The goal of the DDoS flood attack is to make voting server unavailable to voters during election process. In this paper, we present a Multilayer Perceptron (MLP) algorithm to mitigate DDoS flood attack in an e-voting environment and prevent such attack from disrupting availability of the vulnerable voting server. The developed intelligent DDoS flood mitigation model based on MLP Technique was simulated in MATLAB R2017a. The mitigation model was evaluated using server utilization performance metrics in e-voting. The results after the introduction of the developed mitigation model into the DDoS attack model reduced the server utilization from 1 to 0.4 indicating normal traffic. MLP showed an accuracy of 95% in mitigating DDoS flood attacks providing availability of voting server resources for convenient and timely casting of ballots as well as provide for credible delivery of electronic democratic decision making

Password-Based Authentication and The Experiences of End Users

Passwords are used majorly for end-user authentication in information and communication technology (ICT) systems due to its perceived ease of use. The use for end-user authentication extends through mobile, computers and network-based products and services. But with the attendant issues relating to password hacks, leakages, and theft largely due to weak, reuse and poor password habits of end-users, the call for passwordless authentication as alternative intensifies. All the same, there are missing knowledge of whether these password-based experiences are associated with societal economic status, educational qualification of citizens, their age and gender, technological advancements, and depth of penetration. In line with the above, understanding the experience of end-users in developing economy to ascertain their password-based experience has become of interest to the researchers. This paper aims at measuring the experience of staff and students in University communities within southeastern Nigeria on password-based authentication systems. These communities have population whose age brackets are majorly within the ages of 16 and 60 years; have people with requisite educational qualifications ranging from Diploma to Doctorate degrees and constitutes good number of ICT tools consumers. The survey had 291 respondents, and collected data about age, educational qualifications, and gender from these respondents. It also collected information about their password experience in social media network, online shopping, electronic health care services, and internet banking. Our analysis using SPSS and report by means of descriptive statistics, frequency distribution, and Chi-Square tests showed that account compromise in the geographical area is not common with the respondents reporting good experience with passwords usage.Comment: 31 pages, 15 tables, 2 figure

Our analysis using SPSS and report by means of descriptive statistics, frequency distribution, and Chi-Square tests showed that account compromise in the geographical area is not common with the respondents reporting good experience with passwords usage. Furthermore, this experience is not in any way related to their age (under 60), and educational qualification. Our experiment did not measure the entropy of end-users' passwords, their password hygiene culture and so cannot relate this experience with the strengths of their passwords nor that of their password hygiene culture. The outcome and recommendations of this research will help inform policy and research direction towards password hygiene culture, management, and the potentials or otherwise of passwordless authentication systems in developing economies
