Bipolar fully recurrent deep structured neural learning based attack detection for securing industrial sensor networks

Abstract

Attack detection is a significant problem to be resolved to attain security in industrial sensor network. Few research works have been designed for performing attack discovery process with the help of different classification algorithms. However, classification performance was lowered to accurately find attack nodes and thereby getting higher security level (SL). In order to overcome such limitations, bipolar fully recurrent deep structured neural learning based attack detection (BFRDSNL‐AD) technique is proposed in this article. The BFRDSNL‐AD technique comprises of three main layers, namely, input, hidden, and output layer to accurately carry‐out attack detection process. The input layer in BFRDSNL‐AD Technique takes a number of sensor nodes as input. The designed BFRDSNL‐AD technique utilized numbers of hidden layers in order to deeply examine each sensor node in industrial sensor network. The result of the hidden layer is fed‐back into the network along with the inputs in order to discover the temporal dynamic behavior of sensor nodes. In BFRDSNL‐AD technique, output layer applies bipolar activation function to determine the association between identified node features to give attack detection result. If the output layer result is 1, then sensor node is considered as normal. Otherwise, sensor node is considered as malicious attack in industrial sensor network. Thus, the BFRDSNL‐AD technique increases the attack detection performance with higher accuracy and minimal time. From that, BFRDSNL‐AD technique gets enhanced SL in industrial sensor network. The simulation of BFRDSNL‐AD technique is conducted using metrics such as security, data delivery rate, data loss rate, and delay with respect to a different number of sensor nodes and data packets.

Authentication of fog‐assisted IoT networks using Advanced Encryption credibility approach with modified Diffie–Hellman encryption

“…The method is limited to a low-level security model and is not applicable to a high-level security model. 19 introduced an ontology framework for enhancing privacy and 20,21 detected the intrusion in the fog computation network that provided improved robustness and prevented the loss of information. The classifiers used for the detection were optimized using the weed optimization described in Movassagh et al, 22 and these provided optimized results but there is a need for further enhancement.…”

“…Therefore, dutycon proposes a method to dynamically adjust the sleep time C in the node cycle to ensure that the end-to-end delay expecta-tion of the node meets a certain limit [22]. Some researchers began to introduce the routing protocol mentioned in wireless mesh networks into wireless sensor networks [23]. On the whole, the research of network sensors is relatively diverse, but the focus is on transmission.…”
