Improved lightweight security approach routing protocol in internet of things

Many of the devices dealing with the internet of things possessing network and storage capacity shortage are easily susceptible to hacking. In wireless Sensor Networks (WSN), secure data transmission is always a critical issue. Due to the prevalence of malicious attacks, WSN possesses an extensive number of compact, low-cost sensor hubs for gathering secret information. To provide improved secrecy, there is an urge to differentiate malicious nodes from normal nodes. Non-linear substitution is one of the necessary steps in the famous AES cryptosystem. A good quality S-box designing and effective processing time are the remarkable challenges for the rejection of susceptible attacks. The present research introduces an innovative RSA based algorithm and AES KDSB (Advanced Encryption Standard Key Dependent S Box) algorithm. This proposed algorithm with the key-dependent S-Box designation will overcome the limitations of the static S-box. The subkey is developed on the basis of the data block in order to guarantee more security against hacking. The brute force attack broke the data encryption standard since the robust S box used is against replacement. Further, traffic organization with respect to criticality and importance offers a good opportunity for nodes with topmost priority for accessing the channel and capturing the medium. And hence the services are quickly served with minimized delay. The overall efficiency of the suggested system is proved by comparing the framework with the prevailing techniques (BTEM, AF TNS, Trust Doe) with respect to the factors such as throughput, delay, trustworthiness, PDR, False positives and detection rates. Future work regarding the proposed system is also discussed. (C) 2020 Elsevier B.V. All rights reserved.
