Problems solved by technology

[0003] At present, the encrypted database directly stores the ciphertext with the keyword as the granularity in the index. When performing a comparison operation for each query, the index node corresponding to the keyword needs to be loaded into the memory, and then the elements in the index node and the elements to be queried are sequentially compared. The keywords are put into the Enclave (the trusted memory area in SGX, the code and data existing in this area will not be leaked or maliciously tampered with) to decrypt and compare, and then return the comparison results. Frequent Enclave interactions will bring greater extra cost

Abstract

The embodiment of the invention provides a data processing method and device.The data processing method comprises the steps of receiving a data processing request, wherein encrypted target data are carried in the data processing request; decrypting the encrypted target data, and determining a target index node corresponding to the target data based on a keyword of the target data obtained after decryption; when it is determined that the target index node does not have the first cache unit and the first cache unit reaches a preset cache threshold value, determining an adjustment index node in the first cache unit based on a preset strategy; and deleting the adjustment index node in the first cache unit, and writing the target index node into the first cache unit to realize data processing of the target data.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular to a data processing method. One or more embodiments of this specification also relate to a data processing apparatus, a computing device, and a computer-readable storage medium. Background technique [0002] The cloud platform has sound security protection capabilities, which can ensure that the data stored in the database will not be leaked due to external attacks. However, because the data is visible to the cloud platform, users still have concerns about the security of their own data, worrying that internal operation and maintenance personnel will gain unauthorized access to the data or steal user data. Based on these concerns of users, some databases use data encryption for data storage. [0003] At present, the encrypted database directly stores the ciphertext with the keyword as the granularity in the index. When performing a comparison operatio...
