Abstract

A study has been conducted on the current issues of homomorphic encryption schemes, such as their low efficiency and high noise growth rate, which affects the accuracy of decryption. This paper proposed a novel homomorphic encryption scheme for secure multi-party computation based on integer matrices over lattices. This scheme utilized matrix storage to handle plaintext data, reducing the size of the encryption keys. Compared to traditional bit or vector storage methods, the matrix storage approach was more efficient when dealing with large-scale data. To control noise growth and enhance the accuracy of decryption results, it introduced proportional noise reduction technology, effectively mitigating the accumulation of noise. The scheme also employed ciphertext packing and improved the bootstrapping technique to reduce the noise growth rate, providing conditions for secure multi-party computation. It provided rigorous theoretical proofs to validate the correctness and security of the scheme. Experimental results demonstrate that the encryption and decryption times of this scheme are at least 66.97% and 33.04% lower than those of comparative schemes, respectively, showing a significant performance advantage.
