Temporal: Blockchain-based Security Framework for Cyber Physical Systems (BSF-CPS)

SPEAKER
Dr. Abhilasha Vyas

ABSTRACT
Cyber physical systems more commonly known as CPS, is a class of automated systems which work as a lifeline in smart cities’ systems such as home automation system, power grid, automotive industry, etc. CPS are transforming the way we interact, monitor and control the physical world around us. The security aspects of these systems are in high demand as these systems are involved in the day-to-day life of people and the national economy. Compromised CPS can harm the day-to-day operations of people. CPS systems are complex in design and more prone to cyber-attacks. Detection of safety and security deficiencies acts as a fundamental building block for creating a security framework for CPS at different levels. Cyber Physical Devices (CPS), the Internet of Things, and digital frameworks are generally cases of embedded devices in which the basic requirement is to provide flexibility to various applications with higher adaptability to provide reliable communication with the implementation of communication protocols. However, existing platforms use centralised networking, which suffers from security, scalability and big-data problems. In this talk, I will be presenting a blockchain-based security framework for CPS (BCSF-CPS) which will provide a trustable network to get rid of third-party problems. In addition, also improve the scalability, security and big-data problems for CPS. The rudimentary principal behind the proposed framework is based on a hybrid of open and consortium blockchain. This hybrid approach will provide a peer-to-peer communication network between the end user and the service provider. The first half of this talk will present a review of CPS major security problems like centralized control, cloud and edge device data management, heterogeneous environment, secure data access with high latency and accuracy, adversarial attacks, overall security, and privacy. The proposed BCSF-CPS framework will be presented in the second half of the talk. BCSF-CPF based on role-based access using the account address of the blockchain node as the identity, redefining access permissions, designing the initialization, access control, authorization, authorization revocation and audit processes, and using lightweight symmetric encryption algorithm to achieve privacy protection. Moreover, will also share review in applying blockchain technology for CPS to provide insights and highlight the challenges and future opportunities.
