The user demand and data transmission rates are ever increasing in wireless communication networks. However, due to their broadcast structure, wireless connections are inherently risky. In recent years, however, advances in the field of secure wireless communications have been made in the physical layer including beamforming and artificial interference approaches. However, these works are yet to be used for cyber-physical systems (CPS), which will enable us to interconnect all elements of an industrial production process. CPS contain stringent requirements such as a maximum allowed latency, in addition to the commonly known metrics as security capacity. Existing PHY security solutions fail to address these requirements. In our project WiSeCPS, we target to enhance the current PHY security solutions, and provide a target to jointly use different approaches in an optimized fashion according to the requirements of a CPS. Our main goal in this project is to establish a secure CPS communications framework, determine the performance limits and propose applicable security solutions with proof-of-concept hardware demonstrations using software defined radio nodes. With this main goal our objectives are listed below.
- Objective 1: Improvement of the existing wireless security solutions for the CPS secrecy strategies
- Objective 2: Development of a common quality metric for the secrecy strategies in CPS
- Objective 3: Development and application of multi agent optimization concepts with improved secrecy in distributed CPS, to propose a flexible control architecture
- Objective 4: Integration of the strategies in a real test environment using software defined radio nodes to understand performance limits within a proof of concept (PoC) level deployment Objective 5: Proposal of PHY-Security Framework for CPS
