Abstract
A secure two-party real number comparison method and apparatus based on nonlinear mapping can include matching a secure two-party real number comparison protocol based on a real number comparison request, and executing the secure two-party real number comparison protocol on a first secure party real number and a second secure party real number based on a first secure party node and a second secure party node to obtain a first secure party computation result and a second secure party computation result, thereby obtaining a real number comparison result between the first secure party real number and the second secure party real number. The secure two-party real number comparison protocol is determined based on a secure two-party nonlinear mapping protocol and sign conversion processing; the secure two-party nonlinear mapping protocol is determined based on vector space mapping transformation and a secure two-party dot product protocol.
