A New Lightweight Cryptographic Cipher for Detection and Prevention of Replay Attacks in Wireless Sensor Networks

Abstract

Security concerns have been brought up by the electronics industry's widespread use of ubiquitous gadgets. The limitations of power consumption, space, and speed make it impractical to construct a full-fledged cryptographic environment using traditional encryption techniques in embedded systems like the Internet of Things. Lightweight cryptography is the main focus in order to get over these obstacles. This study proposes a new lightweight cryptography cipher that modifies the original PRESENT cipher by introducing a new layer between the S-box layer and P-layer of the current encryption-decryption process, lowering the encryption round, and changing the Key Register updating technique. The delta value function of the lightweight cipher known as the Modified Tiny Encryption Algorithm (MTEA) is added to the key register to update its encryption value. By adding an additional layer, we are able to lower the PRESENT round from 31 to 25, which is the bare requirement for security. Encrypting the key register increases the suggested algorithm's efficiency. By using MATLAB2022a and SIMULINK2022a are product of math work, widely used for mathematical computing algorithm development, data analysis, visualization and simulation.
