我们提出了第一个同态秘密共享（HSS）结构，它同时(1)具有可忽略不计的正确性误差，(2)支持指数级大范围的整数，以及(3)依赖于一个未知的隐含FHE的假设-特别是决策复合残差（DCR）假设。这就解决了Boyle和Gilboa提出的一个开放性问题
We present the first homomorphic secret sharing (HSS) construction that simultaneously (1) has negligible correctness error, (2) supports integers from an exponentially large range, and (3) relies on an assumption not known to imply FHE — specifically, the Decisional Composite Residuosity (DCR) assumption. This resolves an open question posed by Boyle, Gilboa
