Canetti(FOCS 2001)的通用可组合性模型(UC)允许安全地组合任意协议。我们提出了一个量子版本的UC模型，它享有同样的组件性保证。我们证明了在该模型下，可以根据承诺构造统计安全的不经意传输协议。此外，我们还证明了每个统计经典UC安全协议也是统计量子UC安全协议。在其他量子安全定义中，这样的含义是未知的。作为推论，我们得到了用于一般多方计算的量子UC安全协议可以由承诺构造。
The Universal Composability model (UC) by Canetti (FOCS 2001) allows for secure composition of arbitrary protocols. We present a quantum version of the UC model which enjoys the same compositionality guarantees. We prove that in this model statistically secure oblivious transfer protocols can be constructed from commitments. Furthermore, we show that every statistically classically UC secure protocol is also statistically quantum UC secure. Such implications are not known for other quantum security definitions. As a corollary, we get that quantum UC secure protocols for general multi-party computation can be constructed from commitments.
