A chaotic cryptographic solution for low-range wireless communications in Industry 4.0
Industry 4.0 refers the use of Cyber-Physical Systems as main technological component in industrial systems, but also in home and personal applications. Industrial systems tend to be critical, so privacy, trust and security are essential in this new revolutionary era. However, up to this moment, these deployments are most considered unsecure, especially when local-range communication technologies are employed. Very common systems such as the remote controls opening private areas in manufacturing companies are totally unprotected. Although this problem could be not prioritary in traditional production systems, in Industry 4.0 is critical, because of the great interdependency among components and the need of protecting the critical core managing the entire production system of a company. Therefore, in this paper it is proposed a lightweight cryptographic solution to protect low-range wireless communications. The proposed solution is based on chaotic masking technologies, which may be easily implemented in resource constraint embedded devices (as those employed in Industry 4.0). A real implementation of an infrared device including our solution is also described. An experimental validation is performed using the implemented real device.
