Efficient lightweight chaotic secure communication system for WSNs and IoT
Akila Zirem, Mustapha Réda Senouci · 2018
Interconnected embedded devices are the key building block for wireless sensor networks (WSNs) and the Internet of Things (IoT). Many real-life WSNs and IoT applications require cryptographic security mechanisms to ensure data confidentiality during transmission. This paper presents the design of an efficient chaos-based secure communication system and its optimized implementation on an 8-bit microcontroller. The proposed cryptosystem performs one confusion-diffusion round at the byte level by combining the centrifuge operation and the XOR operator. Confusion and diffusion layers are endowed with chaotic sequences from two discrete one-dimensional logistic maps. The efficiency and effectiveness of the proposed cryptosystem are validated at both statistical and implementation levels.
