Despite the great efforts to secure wireless sensor network (WSN), the dynamic nature and
the limited resources of sensor nodes make searching for a secure and optimal network …

Abstract A Wireless Sensor Network (WSN) is comprised of a number of sensor nodes (SNs)
that are randomly placed in an open, harsh environment for many applications. Due to the …

In order to ensure the basic security of wireless sensor networks (WSNs), a block encryption
algorithm based on chaotic substitution box (S-box) is proposed. In this paper, we generated …

This paper proposed a new light weight secure cryptographic scheme for secure image
communication. In this scheme the plain image is permuted first using a sequence of pseudo …
