This specification provides a data truncation method, device, storage medium, and program product for multi-party secure computation. The unsigned representation of a fixed-point product is mapped to a signed representation using signed coefficients, and truncation of the signed representation is performed. Specifically, the truncation process for the target fragment corresponding to the fixed-point product is mapped to a geometric space. In this geometric space, the target fragment is mapped to a Boolean value. Both parties exchange masks of the Boolean values. Bit multiplication is performed based on the local Boolean values ​​and the exchanged masks, generating a signed coefficient fragment based on the bit multiplication result. The target fragment is then converted to a signed fragment based on this signed coefficient fragment, and the signed fragment is truncated to obtain the truncated result. In this process, both parties perform bit multiplication locally, eliminating the need for complex cryptographic primitives. This significantly reduces communication rounds and traffic while ensuring data security, thus improving data truncation efficiency.
