Abstract

The invention discloses a complement arithmetic unit and an arithmetic method based on a multi-key fully homomorphic scheme. The arithmetic unit comprises a multi-key fully homomorphic addition arithmetic unit, a multi-key fully homomorphic subtraction arithmetic unit, a multi-key fully homomorphic multiplication arithmetic unit and a multi-key fully homomorphic division arithmetic unit. The multi-key fully homomorphic adder is composed of a multi-key fully homomorphic 0-class adder; the multi-key fully homomorphic subtractor is composed of a multi-key fully homomorphic 0-class adder and a multi-key fully homomorphic negation device; the multi-key fully homomorphic multiplier is composed of a multi-key fully homomorphic 0-class adder, a multi-key fully homomorphic 1-class adder, a multi-key fully homomorphic 2-class adder and a multi-key fully homomorphic AND gate; the multi-key fully homomorphic divider is composed of a multi-key fully homomorphic complement device, a multi-key fully homomorphic CAS unit and a multi-key fully homomorphic exclusive-OR gate. According to the method, an arithmetic operator for complement integers of any bit is constructed, arithmetic operation between positive and negative integers of any bit can be supported, and the practicability of an MKTFHE scheme is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a complement operator and an operation method based on a multi-key fully homomorphic scheme. Background technique [0002] Privacy computing is a technology that can perform data computing without revealing specific information. Commonly used privacy computing technologies include Homomorphic Encryption (HE), secure multi-party computing technology, and differential privacy technology. [0003] Homomorphic encryption technology is a cryptographic technology based on mathematical problems. After the data that has been homomorphically encrypted is decrypted, the result is the same as the result of using the same method to directly operate on the unencrypted data. At present, fully homomorphic encryption schemes are roughly divided into three generations according to different technical stages. [0004] The first generation: the ideal lattice-based scheme G...
