摘要
The traditional mode of power data transaction is mediated by web pages, which cannot be employed to data explosion as the power trading reform. It is a challenge issue to improve efficiency and privacy under the premise of transaction security and data reliability in power data trading. In this paper, we propose a novelty efficient and secure power data trading scheme (PDTS) based on blockchain and trusted execution environment platform (PDTP). PDTS makes full use of the dispersibility and immutability of blockchain to ensure the reliability of data transaction. It is noteworthy that the power data processing tasks take the form of smart contracts to ensure the efficiency of the transaction process. Meanwhile, trusted execution environment (TEE) is employed to ensure the security of power data processing. Finally, we analyze the security of the scheme and prove that the scheme can resist single point attack, external attack and internal attack. Moreover, the experimental results prove the feasibility and efficiency of the proposed scheme.
