Secure IOT System Based on Chaos-Modified Lightweight AES

The increasing The Internet of Things objects and entities in the famous applications causes a needing to provide an unique and secure identifiers with ability to protected data transferring through the network. Secure IoT communication becomes more urgent issue for important IOT entities that content computing-devices and embedded-sensor subsystems used in unofficial industrial machine to machine (M2M) communications, smart energy-grids, home or buildings and other computing devices. In this paper we proposed a secure system by using chaotic system combinate with the modified lightweight AES. The 5-D chaos system (hybrid from logistic and Lorenz chaotic system) was used to generate the sequences chaos keys used in the lightweight AES and SHAKE128. The Lightweight AES was modified to reduce the processing complexity of AES with decreased the processing time (have 145% speed more). The output of modified lightweight AES encryption System has the good statistical tests near to original AES that can avoid many attacks.
