[0003] However, in the existing technology, there is no guarantee for the security of the underlying operators in the spark query. During the running process, the data in the calculation can be obtained by dumping the memory (obtaining the memory image), and the security of the calculation cannot be guaranteed.

Abstract

The invention discloses a spark inquiry method and a system supporting trusted calculation. The method comprises steps of receiving an SQL query sentence input by a user; Parsing the SQL query sentence, analyzing the logical plan, optimizing the logical plan and generating the physical plan; The operator in the physical plan is reimplemented by adopting the SGX API to generate an execution code; The enc lave trusted environment is invoked to implement trusted computation of the operator, and the execution code is executed. The invention ensures the safety of the data in the calculation processwhile processing the query request in parallel through the spark structure. Moreover, the spark interface provides users with more user-friendly services.

Description

【Technical field】 [0001] The invention relates to computer application technology, in particular to a spark query method and system supporting trusted computing. 【Background technique】 [0002] In recent years, with the popularization and application of the Internet, the Internet of Things, and smart terminal devices, data is generated faster and larger, and in order to provide TB-level big data queries, the spark architecture is mainly used to Process data in parallel at scale. Among them, Spark is a general parallel framework of Hadoop MapReduce open sourced by the AMP Laboratory of the University of California, Berkeley. [0003] However, in the existing technology, there is no guarantee for the security of the underlying operators in the spark query. During the running process, the data in the calculation can be obtained by dumping the memory (obtaining the memory image), and the security of the calculation cannot be guaranteed. 【Content of invention】 [0004] Variou...
