Designing a user authentication protocol for wireless sensor networks is a difficult task
because wireless networks are susceptible to attacks and sensor node has limited energy …

The architecture of two-tiered sensor networks, where storage nodes serve as an
intermediate tier between sensors and a sink for storing data and processing queries, has …

The widely deployed Virtual Private Network (VPN) technology allows roaming users to
build an encrypted tunnel to a VPN server, which henceforth allows roaming users to access …

Most large-scale sensor networks are expected to follow a two-tier architecture with resource-
poor sensor nodes at the lower tier and resource-rich master nodes at the upper tier. Master …

Cloud-based Personal Health Record systems (CB-PHR) have great potential in facilitating
the management of individual health records. Security and privacy concerns are among the …

Wireless sensor networks (WSNs) are vulnerable to security attacks due to their deployment
and resource constraints. Considering that most large-scale WSNs follow a two-tiered …

Storage nodes are expected to be placed as an intermediate tier of large scale sensor
networks for caching the collected sensor readings and responding to queries with benefits …

Two-tiered wireless sensor networks offer good scalability, efficient power usage, and space
saving. However, storage nodes are more attractive to attackers than sensors because they …

Integrity and privacy are two important secure matrices in cyber security. Due to the limited
resources and computing capability of the sensor nodes, it is challenging to simultaneously …
