Question Details

您好,我们想了解下是否可以通过隐语实现两个机构间,在保障数据不出域条件下,利用双方数据进行业务计算,包括实现 双方数据的加减乘除,谢谢
具体问题如下:
1,scql中的除法是怎么实现的,经过了解隐私计算目前不支持除法,目前咱们通过scql是通过明文计算吗,是怎么实现的,来保障数据不会泄露的
2,在secretpad中可以通过二元运算的方式怎么实现的除法的,在求交完后,生成的整个表之间运算是明文计算的吗,如何保障双方数据不泄露,而且计算的加减乘除的计算是通过什么方式实现的

Hi @ShaneGu4Real

无论是secretpad还是scql,多方安全计算(MPC)都依赖SPU的能力。详情请阅读文档:https://www.secretflow.org.cn/en/docs/spu/0.9.3b0/。

一般来说,除法不属于MPC协议基本操作,我们一般会通过近似的方法处理,可以看一下这篇文档:https://www.secretflow.org.cn/en/docs/spu/0.9.3b0/development/fxp#Div
