Gridchain: An Auditable Blockchain for Smart Grid Data Integrity and Immutability—InfoBeyond Technology, LLC, Louisville, KY, 320 Whittington Parkway Suite 117, Louisville, KY 40222-4917 Bin Xie, Principal Investigator, Bin.Xie@InfoBeyondtech.com Bin Xie, Business Official, Bin.Xie@InfoBeyondtech.com Amount: $1,081,501 We have been witnessed the Industroyer power grid cybersecurity attack in Ukraine’s power system in which attackers controlled the substation’s circuit breakers and protection relays. In 2018, CyberwarCon forum in Washington, DC reported that a variety of hacker groups (e.g., Russian Energetic Bear) have been targeting to the U.S. power grids. For defending these attacks, grid data integrity and immutability must be maintained in the all phases of data generation, delivery, store, and consumption. However, it is still a security problem To fill up this security gap, InfoBeyond propose Gridchain (An Auditable Blockchain for Smart Grid Data Integrity and Immutability) that advocates blockchain technology to achieve grid data integrity and immutability. Specifically, the proposed Gridchain has three software components: (i) Data Feeding Authentication (DFA), (ii) Grid Blockchain, and (iii) Auditor. DFA integrates OpenFMB to retrieve the data of interests from endpoints and securely feed to blockchain contracts. It leverages trust computing to act as a security bridge between OpenFMB and Blockchain. Grid Blockchain employs a two-layer Ethereum structure (e.g., Macro and Micro Contracts) to achieve high throughput transactions in support of a large scale grid network. Further, Auditor is an online auditing module to add the security to prevent dishonest or malicious grid contracts. It analyzes the contracts to detect blockchain misbehaviors from attackers. Gridchain is innovative: (i) It is the first attempt that combines OpenFMB and Software Guard Extension (SGX) technology to enable that the grid data generated at endpoints are trustworthily fed into the blockchain ecosystem; (ii) It is the first attempt that uses auditing technology to prevent misbehavior (e.g., mishandling smart contracts) caused by attackers. Gridchain is designed for the capabilities to ensure grid data integrity and immutability. It addresses the urgent requirements of national power systems to improve grid security and resilience against cybersecurity attacks. Once developed as COTS/GOTS products, it provides significant values for the DoE and power industry: America’s electric grid is critical for national security, economy, and society. Gridchain provides a new method for grid data protection of integrity and immutability to a new level by taking advantage of blockchain technology. Additionally, a high level of power grid data protection is especially more important to U.S. military mission operations and defense. Gridchain improves the smart grid service security that protects the service availability and efficiency. It promotes economical and clean energy distribution that securely integrates communication, advanced control methods, and decision support using grid data. Gridchain reduces the cost by greatly eliminating the need for system operators to manage the smart grid. Moreover, human errors can be greatly eliminated as the transactions are initiated using self-enforced grid contracts.
