Abstract

Cooperative encryption and decryption is an important research direction in secure multi-party computation. It can achieve data protection and privacy protection safely and efficiently. To solve the problem of high computational complexity in the offline calculation phase of existing SM4 collaborative encryption and decryption schemes, this paper proposed a new SM4 collaborative encryption and decryption scheme based on oblivious polynomial evaluation. The scheme utilized pre-calculated polynomial sets and sets of polynomial values to complete S-box collaborative computation in the online stage, thereby improving the performance of the online calculation stage. This paper proved the correctness and security of the proposed scheme, and compared with four different schemes, the results show that the computational efficiency of the proposed scheme is significantly higher than that of other schemes. This shows that the proposed scheme can complete SM4 cooperative encryption and decryption safely and efficiently.
