在这篇文章中,我们展示了如何将一个统计绑定但计算隐藏的量子比特承诺方案转换成一个计算绑定但统计隐藏的量子比特承诺方案。对于安全参数n,统计隐藏方案的构造需要O(N2)次统计绑定方案的执行。因此,统计上隐藏但在计算上具有约束力的量子比特承诺可以基于任何一族量子单向函数。这样的结构在古典世界中是不存在的。
In this paper we show how to convert a statistically binding but computationally concealing quantum bit commitment scheme into a computationally binding but statistically concealing qbc scheme. For a security parametern, the construction of the statistically concealing scheme requiresO(n2) executions of the statistically binding scheme. As a consequence, statistically concealing but computationally binding quantum bit commitments can be based upon any family of quantum one-way functions. Such a construction is not known to exist in the classical world.
