  In an endeavor to reach the vision of ubiquitous computing where users are
able to use pervasive services without spatial and temporal constraints, we are
witnessing a fast growing number of mobile and sensor-enhanced devices becoming
available. However, in order to take full advantage of the numerous benefits
offered by novel mobile devices and services, we must address the related
security issues. In this paper, we present results of a systematic literature
review (SLR) on security-related topics in ubiquitous computing environments.
In our study, we found 5165 scientific contributions published between 2003 and
2015. We applied a systematic procedure to identify the threats,
vulnerabilities, attacks, as well as corresponding defense mechanisms that are
discussed in those publications. While this paper mainly discusses the results
of our study, the corresponding SLR protocol which provides all details of the
SLR is also publicly available for download.
