Context-Adaptive Information Security for UbiComp Environments

TLDR: Traditional computer applications expect a static execution environment, but this assumption is no longer realistic in the Ubiquitous world scenario, where the environment around a piece of information, contained on a device or within a communications channel, is frequently changing.

Abstract: Traditional computer applications expect a static execution environment. Such environments imply nonor slowlyevolving information security and privacy threat models. This assumption is no longer realistic in the Ubiquitous world scenario, where the environment around a piece of information, contained on a device or within a communications channel, is frequently changing. Thus, the information contained in the Ubiquitous world is exposed to varying threat models throughout its lifetime. Users expect high degree of information availability anytime and anywhere as needed, leading to serious security and privacy risks and access control problems.
