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
