Power consumption of a chaos-based stream cipher algorithm

With the huge usage of the Internet of Things (IoT), lots of sensitive data are being transferred between devices. This raises the need for security so that unauthorized parties can’t access the data. IoT devices are known to have limited resources; they have limited battery life, limited memory size and their response time should be minimized. With these speed and memory constraints, classical encryption systems and methods don’t work efficiently with the IoT devices, because they can be too slow, huge or very power consuming. Here comes the need to develop a Lightweight cryptosystem that meets the requirements of the Lightweight device. In this paper, a practical lightweight stream cipher based on stream cipher is proposed, then the power consumption is calculated to show the suitability for limited resources devices. Furthermore, some lightweight measurement tools will be used in order to achieve the research objectives.
