论文摘要
半源独立量子步行随机数发生器(SI-QW-QRNG)是一种加密协议,它从带有对手的量子随机步行中提取一串真实的随机位,可控制随机性源,但已知系统的尺寸。本文用基于内存的量子步行状态分析了SI-QW-QRNG协议。新协议利用具有各种参数的广义硬币运算符来优化量子步行状态的随机性。我们专注于在多种方案和步行配置中对协议的评估。此外,我们根据内存空间的大小和量子硬币的数量显示了系统的一些有趣行为。
The semi-source independent quantum walk random number generator (SI-QW-QRNG) is a cryptographic protocol that extracts a string of true random bits from a quantum random walk with an adversary controls a randomness source, but the dimension of the system is known. This paper analyzes SI-QW-QRNG protocols with a memory-based quantum walk state. The new protocol utilizes a generalized coin operator with various parameters to optimize the randomness of the quantum walk state. We focus on evaluations of the protocols in multiple scenarios and walk configurations. Moreover, we show some interesting behavior of the system depending on the size of the memory space and the number of quantum coins.
