Secure and Efficient Data Storage in Unattended Wireless Sensor Networks
Ren, Yi; Oleshchuk, Vladimir A.; Li, Frank Yong (Journal article; Peer reviewed, 2009)Providing forward and backward secrecy is still a big challenge in Unattended Wireless Sensor Networks (UWSNs), though some storage schemes have been proposed. Additionally, high storage requirement needs efficient storage ... -
Secure, dependable and publicly verifiable distributed data storage in unattended wireless sensor networks
Ren, Wei; Ren, Yi; Zhang, Hui (Journal article; Peer reviewed, 2010)In unattended wireless sensor networks (UWSNs), sensed data are stored locally or at designated nodes and further accessed by authorized collectors on demand. This paradigm is motivated by certain scenarios where historical ... -
Security in mobile wireless sensor networks - A survey
Ren, Yi; Oleshchuk, Vladimir A; Li, Frank Yong; Ge, Xiaohu (Journal article; Peer reviewed, 2011)Thanks to recent advances in robotics, sensors and wireless communications, it is feasible to develop a variety of new architectures for Mobile Wireless Sensor Networks (MWSNs) that play an important role in various ... -
A spatial role-based authorization framework for sensor network-assisted indoor WLANs
Ren, Yi; Oleshchuk, Vladimir A; Li, Frank Yong (Chapter; Peer reviewed, 2009)In this paper, we propose a spatial role-based authorization framework which specifies authorization based on both role and location constrains in a wireless local area network with assistance from a sensor network. The ...
