The FOG-CPS security lab of IIIT-Allahabad and Cardiff University, UK are jointly organizing a "2 Days International Workshop on CYBER PHYSICAL SYSTEMS SECURITY" during August 21-22, 2023. The event will be sponsored by the Centre for Cyber Security and Cyber Defence of Critical Infrastructures (C3i HUB), Indian Institute of Technology, Kanpur. Cyber Physical Systems (CPS) combines the physical and digital realms, allowing for real-time control of operations. However, this integration raises security concerns. As CPSs are used in important industries like manufacturing and healthcare, their susceptibility to attackers grows. Malicious activities have the potential to disrupt operations and harm lives. Securing CPSs necessitates measures such as robust authentication, encryption, and constant monitoring to discover abnormalities as soon as possible. Finding the correct combination of connection and security is critical for reaping the benefits of CPS while reducing dangers. In this workshop, scientists from the top academic institutions over the globe will provide an overview on the current trends in CPS security research challenges. Researchers from Industry, Government Organisations, Faculty, and PhD, PG/UG students are encouraged to attend the event and interact with the speakers. The workshop will be conducted in hybrid mode where participants from outside IIITA can join in online mode only. An E-Certificate of participation will be awarded to each participant. More details about the workshop can be found in the attached flyer or on the conference website.
