Several symmetric-key distribution mechanisms are proposed in the literature, but most of
them are not scalable or they are vulnerable to a small number of captured nodes. In this …

Many mission critical wireless sensor networks require an efficient, lightweight and flexible
intrusion detection algorithm to identify malicious attackers. In this paper, we propose a …

Key encryption technology is a basic technique for protecting the secrecy of transmitted data
among sensor nodes in wireless sensor networks. However, sensor nodes are inherently …

Modern wireless sensor networks have adopted the IEEE 802.15. 4 standard. This standard
defines the first two layers, the physical and medium access control layers; determines the …

We present an approach for privacy preservation in cloud computing environment in which
we propose to use information entropy and rough set theory with the goal of personalized …

In this paper, we propose a novel identity-based random key pre-distribution scheme called
the identity based key pre-distribution using a pseudo random function (IBPRF), which has …

Key establishment in sensor networks is a challenging problem because of resource
constraints of the sensors. Due to resource limitations and vulnerable to physical capture of …

Locally parallel dense patterns-sometimes called texture flows define a perceptually
coherent structure which is important to image segmentation, edge classification, shading …

In this paper, we propose a novel key management scheme based on genetic algorithms to
fulfill the requirement of power control, memory usage, and computation security in a …

The exclusion basis system is a combinatorial formulation of group key management that
provides long-term and flexible protection for wireless sensor networks while allowing for …
