For preventing malicious nodes joining wireless sensor networks (WSNs), an access control mechanism is necessary for the trustworthy cooperation between the nodes. In addition to access control, recently, privacy has been an important topic regarding how to achieve privacy without disclosing the real identity of communicating entities in the WSNs. Based on elliptic curve cryptography, in this paper,...
As sensors become ever more prevalent, more and more information will be collected about each of us. A long-term research question is how best to support beneficial uses while preserving individual privacy. Presence systems are an emerging class of applications that support collaboration. These systems leverage pervasive sensors to estimate end-user location, activities, and available communication...
The seamless combining with context-aware sensors and numerous devices and e-home server will soon become a part of our home environment in the near future. We name it as a context-aware home based on ubiquitous computing concept. This context-aware home reduces participations of users in order to realize a ubiquitous computing and automates various services. Therefore, the risk of privacy violation...
