The evolution of digital communication era includes both devices and applications running on different platforms. Specifics applications are needed for a safeguard communication ensuring protection and trust services to the users. This paper presents an authentication and session-key establishment protocol that enabling mutual authentication procedure between involved entities in the WSNs. This scheme...
The problem of key management in ad hoc networks was analyzed in this paper. Key management, however, can reveal information about the dynamics of ad hoc network membership, such as the group size and the number of joining and leaving users. Thus, only legitimate members have access to the messages. Once any member in the ad hoc network was going to join or leave the group, the group key would be...
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...
Information privacy is usually concerned with the confidentiality of personally identifiable information (PII), such as electronic medical records. Nowadays, Web services are used to support different applications which may contain PII, such as healthcare applications. Thus, the information access control mechanism for Web services must be embedded into privacy-enhancing technologies. Further as application...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
