Abstract
This specification discloses a data sorting method and apparatus, a device, and a readable storage medium. In the data sorting method provided in this specification, a non-reference ciphertext is updated based on a first noise value corresponding to the non-reference ciphertext and a first specified parameter, and each non-reference ciphertext is compared with an updated reference ciphertext. Further, a to-be-processed array is divided into a plurality of subarrays based on a first comparison result. Each subarray is separately re-used as a to-be-processed array. The above-mentioned comparison process is repeated until each array includes only a single ciphertext. A sorting result of each ciphertext is determined based on a size relationship between the arrays.
