Challenges and Solutions for Blockchain-based Cyber Physical Systems
- Unauthorized access or theft of cryptographic keys may lead to total loss of data
- Improper key management and access control, unintended forks and chain split attacks are concerns
- API integration with third parties leads to trust issues
- Blockchain can provide security for smart systems and achieve trusted data storage and execution of smart contracts
- Security and privacy are significant challenges in cyber physical systems
- Heterogeneity in device resources, multiple attack services, lack of control over data sharing, and poor implementation of security and privacy mechanisms are challenges
- Audit facilities and updating software and hardware are important
- Ransomware attacks are a major threat to cyber physical systems
