    Security of Internet Transactions
    (Springer, 2009) Musau, F.; Ren, S.; Yu, Shouyi
    State-of-the-art IT facilities are ever more frequently applied in all areas of life. Nowadays, Internet connection, online resources and services are taken for granted. It is much quicker (almost immediate) and more convenient to access electronic information and use online services than to employ traditional methods. Therefore, more and more people take advantage of these options. Aware of the benefits, they often forget about network threats (that arise from inappropriate software protection and failure to follow necessary security rules) or simply underestimate them. This chapter deals with threats to Internet transactions with particular emphasis on new ways of obtaining information and data under false pretences and threats to services rendered in wireless networks.

    Transparent Computing: A New Paradigm for Increased user Friendliness in Service Sharing
    (2013) Musau, F.; Obiria, P. B.
    Due to the research and technological advances, ubiquitous or pervasive computing is emerging rapidly as an exciting new discipline to provide computing and communication services all the time and everywhere. While with many ongoing initiatives, it is too far to achieve the vision that Mark Weiser described. After a comprehensive analysis on traditional paradigms, we argue that, not users-friendly, i.e., users can not get services from computer easily, is one of the main reasons. In this paper, a new computing paradigm, i.e., Transparent Computing will be presented to solve this problem partially. Accordingly, we propose and develop a pilot system, which runs in a network environment and operates at the assembler instruction level. This system lets users demand heterogeneous OSes and applications upon them from centered simple servers, similar to choose different TV channels in daily life. We also present some primitive real and experimental results to show that it is a feasible and efficient solution for future computing infrastructure.
