This document outlines a presentation on Internet of Things (IoT) security using stream ciphers. It discusses defining IoT and related challenges, key security technologies like encryption, and cryptography methods like the one-time pad. It proposes using a linear feedback shift register as a pseudo-random number generator for a one-time pad stream cipher combined with DNA computing. The implementation would encrypt and decrypt messages between Raspberry Pi IoT nodes over the MQTT protocol as a case study for a vehicle network.
