Abstract
Blockchain is a distributed ledger technology that can provide trustworthy data services and robust support for secure data sharing. However, it faces the challenge of data privacy leakage during application, greatly limiting its scope and application areas. With the increasing volume of on-chain data, ensuring privacy protection during the blockchain data query process has become one of the key concerns for researchers. To address this issue, this paper proposes a framework called Trusted Execution Environment-based Blockchain Query Framework (TEEBQF). This framework loads blockchain query transactions based on smart contracts into a trusted execution environment, authenticates the trusted execution environment with relevant cryptographic techniques, and protects the confidentiality of query content, thereby achieving privacy protection during the data query process. Finally, the effectiveness of this framework is analyzed through performance evaluation, confirming its ability to provide robust support for privacy protection during blockchain data queries while achieving efficient and available queries, thus contributing to secure data sharing in blockchain environments.
