Data processing method and device, equipment and storage medium

The invention provides a data processing method and device, equipment and a storage medium, and the method comprises the steps: constructing an n-dimensional plaintext vector based on n to-be-processed plaintext messages with a corresponding relation, taking the n-dimensional plaintext vector as a to-be-processed plaintext vector, coding the to-be-processed plaintext vector, obtaining a code text corresponding to the to-be-processed plaintext vector, and storing the code text in a database; the code text is sent to the code text operation end, a code text operation result returned by the code text operation end is received, the code text operation result is decoded, a plaintext vector corresponding to the code text operation result is obtained, and the plaintext vector corresponding to the code text operation result is used for providing a plaintext message for the target operation requirement. According to the embodiment of the invention, the n to-be-processed plaintext messages with the corresponding relati
