A Novel Secure End-to-End IoT Communication Scheme Using Lightweight Cryptography Based on Block Cipher

Personal data security is a cybersecurity trend that has captured the world’s attention. Governments, practitioners and academics are jointly building personal in various communication systems, including IoT. The protocol widely used IoT implementation MQTT. By default, MQTT does not provide features form of encryption. Therefore, this research was carried out on design Secure End-to-End Encryption with Block Cipher-Based Lightweight Cryptography. designed by utilizing Galantucci secret sharing scheme lightweight cryptographic algorithm based block cipher. algorithms include AES-128 GCM mode, GIFT-COFB, Romulus N1, Tiny JAMBU. We tested for ARM M4 ESP8266 processors. Our testing results NodeMCU board, JAMBU have an average encryption time 313 μs decryption 327 μs. mode 572 584 GIFT-COFB 1094 1110 Meanwhile, N1 2157 2180 On STM32L4 discovery, had 82 85 163 164 165 605 607 experiment shows fastest performance produced JAMBU, followed Mode GCM, N1.
