Abstract
With the increasing use of sensors and intelligent devices, Internet of Things (IoT) becomes an important area of research to establish connectivity among connected devices. Traditional algorithms used for encryption are found to be highly complex and with higher number of rounds for encryption which is computationally expensive. In an IoT network, communicating nodes adapt fewer complex algorithms for maintaining security. Hence, lightweight security algorithms are used for this purpose. In this paper, we have proposed a method for encryption and decryption process called Enhanced Secure IoT (ESIT) of an image using shift (<< or > >) and bitwise binary modulo 2 (+2) operation for data transmission. It is a block cipher that accepts a 64-bit key which performs Left shift (<<) and (+2) function for encryption, and right shift (>>) and (+2) decryption. It is the normal bitwise left and right shift by removing the sequence of q-bits from the left and right side, respectively. The performance of the proposed method is established by correlation, entropy, and image histogram. Experimental evaluation on four available images clearly shows the advantages of the given approach.
