Security is assumed to be one of the key issues of smart
environments. Not only is it critical for the connected devices
and users but it is also dangerous for the gateways that are
connected to them. The issue for security and emergency
response in mission critical communications and infrastructure
is always an important topic especially for mobile ad-hoc
networks (Fragkiadakis et al., 2011; Askoxylakis et al., 2011). In
addition, military applications, factories and industries,
bridges, medical and health and environmental applications
are some examples where security threats should be taken
into consideration. Moreover, the widespread use of smart
objects in the home environment endangers disclosing
private data. For instance, a wireless installed camera, for
recording possible intruders, connected to an insecure home
network could be a susceptible threat to disclose the private
actions of a family. The fast growth of life-logging applications
and the potential for integrating them into smart environments
mandated that security issues need to be addressed.
Secure and trustworthy life-logging in smart environments
involves challenges, risks and threats on the communication
layer under the IoT and finally on the end-users who log on
and interchange data with their smart objects.
