The embodiments of this specification provide a method and device for fusion processing of truncation and ring-raising in secure multi-party computing. The method includes: the first party uses the first ring arithmetic slice of its own party to perform a first multi-party joint calculation with the second party to obtain the Boolean slice of its own party with an overflow indication bit; the overflow indication bit is used to indicate whether the sum of the two first ring arithmetic slices of the target private data overflows the first ring; the Boolean slice of its own party with the overflow indication bit is used to perform a second multi-party joint calculation with the second party to obtain the overflow bit arithmetic slice of the overflow indication bit secretly shared on the second ring; the number of bits of the second ring is determined according to the number of bits of the first ring, the number of bits of the target ring of the ring-raising, and the number of bits of the truncation; based on the first ring arithmetic slice of its own party and the overflow bit arithmetic slice, a local operation is performed to obtain the target ring arithmetic slice of the target private data that is secretly shared on the target ring after truncation. It can significantly reduce the number of communication rounds and communication volume.
