Embodiment Construction

[0028] At present, in order to encrypt and rewrite the database query code, the developer of the client needs to write encryption and rewriting rules. The applicant found through research that in practical applications, database query codes usually involve various complex situations, and the encryption rewriting rules can only encrypt and rewrite some simple database query codes, but cannot perform complex database query codes. Perform correct encryption and rewriting, and the versatility is poor.

[0029] In order to solve the above problems, the embodiment of the present application provides an encrypted rewriting scheme for database access statements, that is, to obtain operation information from the database to be accessed, so as to perform type inference on each operation object in the database access statement based on the operation information of the database. It is determined whether each operation object needs to be encrypted, and the encrypted rewriting of any databa...

Abstract

Embodiments of the present application provide a data processing method, communication system, equipment, product, and storage medium. Wherein, the method includes the following steps: according to the database access statement, determine the operation element contained in the database access statement and the operation object corresponding to the operation element; in the operation object, determine the corresponding to the database field in the database A target operation object; according to the operation element and the target operation object, obtain relevant information from the database; according to the relevant information, determine the target operation information corresponding to the operation element, and the target operation information includes the target An operation object type; the target operation object type includes one of a plain text type and a cipher text type; according to the target operation information, the database access statement is encrypted. The solutions provided in the embodiments of the present application have better versatility.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data processing method, communication system, equipment, product and storage medium. Background technique [0002] The cloud platform has sound security protection capabilities. Therefore, when users use the cloud database, they do not have to worry about the database being hacked from the outside and causing data leakage. However, user data is visible to the cloud platform, which causes users to still worry about unauthorized access by the internal staff of the cloud platform or being used by the cloud platform. [0003] At present, some cloud databases use technologies such as TEE (Trusted Execution Environment, Trusted Execution Environment) to realize retrieval and calculation based on ciphertext. In this way, the user can store the encrypted user data in the cloud database, and the cloud database side cannot obtain the plaintext encryption key of the u...
