基于量子电路的门限量子秘密共享方案

Threshold Secret Sharing Scheme Based on Quantum Circuit

对(n, n)门限量子秘密共享方案参与者人数n为任意的情形(即不局限于n=4k+1?,k∈Z^+)进行了研究,根据量子电路作用在量子态上的性质构造了一个(n, n)门限量子秘密共享方案,进而由Clifford群门和T门组成的可证明安全的量子电路进行安全性评估。最后,对不诚实的参与者攻击进行了安全性分析。

We study a(n,n)threshold quantum secret sharing scheme,where the number of participants is arbitrary(the number of participants is not limited to n=4 k+1,k∈Z^+).And a threshold quantum secret sharing scheme is constructed according to the properties of quantum circuits acting on quantum states,in which the quantum circuit is a provably secure quantum circuit composed of Clifford group gates and T gates.Finally,we use the property of the quantum circuit to analyze the security against dishonest participant attacks.
