Abstract

The invention relates to a cipher state custom operation interpretation system and method. The cipher state custom operation interpretation system comprises: at least one user terminal held by a user; and the server that is in communication connection with the user terminal through a network, in which the expression construction part is used for constructing an infix expression containing at least one built-in function according to the operation requirement of a user; the conversion part is used for converting the infix expression into a suffix expression; the function operation part performs operation on at least one built-in function in the suffix expression one by one according to the ciphertext data to obtain a corresponding function operation result; the replacement part is used for replacing a built-in function in the suffix expression with a corresponding function operation result so as to obtain a new suffix expression; the analysis operation part is used for carrying out analysis operation on the new suffix expression by adopting a preset operation method according to the ciphertext data to obtain a ciphertext expression operation result; and the decryption part is used for decrypting the ciphertext expression operation result to obtain a plaintext expression operation result.

Description

technical field [0001] The invention belongs to the technical field of data security, and in particular relates to a system and method for explaining self-defining operations of encrypted states. Background technique [0002] The ciphertext computing technology can solve the privacy and security issues of outsourcing sensitive data to untrusted cloud servers, thereby greatly reducing the computing overhead of users. This technology has great potential in many practical applications, such as cloud Assisted electronic diagnosis and treatment system, etc. [0003] However, at present, most of the calculation operations on ciphertext are realized through program simulation, and users cannot perform custom calculations, which makes the program lack a certain degree of flexibility. Contents of the invention [0004] The present invention is made to solve the above-mentioned problems, and the purpose is to provide a system and method for user-defined calculation and interpretati...
