。程序员习惯了 IEEE 双精度算术的舍入和误差属性,但是在安全计算范例中,例如多方计算 (MPC) 提供的,通常为实数算术提供不同形式的近似。我们比较了使用基于 LSSS 的 MPC 的两种标准变体,以及使用基于二进制电路的 MPC 实现符合 IEEE 标准的双精度。我们比较了相对性能,并得出结论:对于某些应用程序来说,IEEE 合规性的额外成本可能太大。因此,在安全领域,标准机构可能希望检查不同形式的实数近似值。
. Programmers are used to the rounding and error properties of IEEE double precision arithmetic, however in secure computing paradigms, such as provided by Multi-Party Computation (MPC), usually a different form of approximation is provided for real number arithmetic. We compare the two standard variants using for LSSS-based MPC, with an implementation of IEEE compliant double precision using binary circuit-based MPC. We compare the relative performance, and conclude that the addition cost of IEEE compliance maybe too great for some applications. Thus in the secure domain standards bodies may wish to examine a different form of real number approximations.
