Abstract
The present disclosure provides an end-to-end efficient privacy-preserving computation apparatus and method for secure two-party matrix inversion, relating to the technical field of privacy-preserving computation. In the present disclosure, the respective corresponding output matrices are determined using the privacy-preserving computation request and the private data matrices and then sent to the requesting party of the secure two-party inversion computation, so that the requesting party obtains the final inversion computation result. This solves the problems of large computation and communication overhead in ciphertext space caused by the introduction of homomorphic encryption and oblivious transfer techniques in the prior art, as well as the privacy and security issues caused by the leakage of original data and the loss of precision in floating-point number calculation due to the limitation of fixed-length digits in ciphertext computation.
