To secure the communication in powerful Internet of Things using innovative post-quantum cryptographic method

In general, the Internet of Things (IoT) is used for many applications and plays an essential role in the digital communications of smart city applications. However, securing the sensor-based IoT communication is difficult because it is highly vulnerable to malicious actions like Denial of Service (DOS), ransomware, and node impersonation. In the past several works were presented like Diffie–Hellman, supersingular isogeny, Merkle hash tree, etc., to secure the IoT communication. But, those techniques failed to identify the malicious events, which happened unexpectedly. Also, these procedures were limited to predict malicious events as the harmful attacks look like normal users. Hence, to enhance the privacy measure in IoT communication, a novel post-quantum cryptography (PQC) algorithm is introduced in this research. Here, powerful IoT devices concern with smart devices such as smartphones, smart security systems, and smartwatches. Furthermore, this paper has introduced a novel Diffie Supersingular Multiplication (DSM) for securing communication in powerful IoT devices. The developed approaches were validated by launching the Mirai botnet attack in the transmission channel. Moreover, the proposed DSM model has been implemented using the Xilinx ISE14.5 tool, which has improved 30% frequency, 24% area, 10% confidential rate and also has reduced the power up to 15%, error 10% and 20% delay, which are quite better than other compared techniques.
