Implementation and performance analysis of AES-128 CBC algorithm in WSNs

Abstract

The sensor networks is a network technique for the implementation of Ubiquitous computing environment. It is wireless network environment that consists of the many devices, called the sensor node, which have miniature computing device, small memory space and very limited battery power. Though sensor network provides various capabilities, it is unable to ensure the secure authentication between sensor nodes. Eventually it causes the losing reliability of the entire network and many secure problems. Therefore, Symmetric key encryption algorithm with low-Energy consumption is required to the applicable sensor networks. In this paper, we proposed the solution of reliable sensor networks to analyze the communication efficiency through measuring performance of AES-128 CBC algorithm which is selected by default in sensor networks by plaintext size and cost of operation per hop according to the network scale.
