Blockchain Based Data Storage Mechanism in Cyber Physical System
作者 Jin WangWencheng ChenYongjun RenOsama AlfarrajLei Wang
英文摘要
As cyber-physical systems (CPS) flourish, the data security issues it encounters have increasingly become a research focus in the field. And it has received widespread attention from academia and industry. Blockchain technology has the characteristics of decentralization, openness, transparency, reliability and non-tampering. It has natural advantages in solving the security of the CPS. Thus, this paper first analyzes the security risks associated with data storage in cyberphysical systems and proposes the use of blockchain technology to ensure the secure storage of data in CPS. In traditional blockchains, the data layer uses Merkle hash trees to store data; however, the Merkle hash tree cannot batch add/delete and provide non-membership proof. In order to solve this problem, this paper improves the accumulator and uses the combination of accumulator and Merkle hash tree to provide batch addition/removal and non-membership proof. This paper constructs a Merkle hash tree accumulator, and proves that the scheme is feasible through correctness and security.
