摘要:

在过去的几十年里,量子技术取得了持续的进步,量子计算机领域的最新发展引人注目。传统上,这种趋势主要被视为密码学的严重风险;然而,量子技术的积极方面也应该得到强调。在这方面,将该技术视为诚实方而不是对手的资源,它不仅可以增强安全性,还可以增强特定加密方案的性能。虽然相当大的努力已经投入到量子抵抗和量子增强方案的设计,很少有人努力了解他们的物理安全性。物理安全涉及安全措施的设计和实现,以满足密码原语的实际要求,这对经典和量子密码同样重要。本调查旨在引起人们对物理安全重要性的更多关注,重点关注安全密钥生成和存储以及安全执行。更具体地说,在量子世界中进行侧信道分析的可能性进行了讨论,并与经典世界中发起的攻击进行了比较。此外,量子随机数产生和量子物理不可克隆函数的建议进行了比较,并进一步分析,以更好地了解他们的特点,优点和缺点。最后,从这三个角度出发,对该方向的未来研究进行了展望。

英文摘要:

Over the past decades, quantum technology has seen consistent progress, with notable recent developments in the field of quantum computers. Traditionally, this trend has been primarily seen as a serious risk for cryptography; however, a positive aspect of quantum technology should also be stressed. In this regard, viewing this technology as a resource for honest parties rather than adversaries, it may enhance not only the security, but also the performance of specific cryptographic schemes. While considerable effort has been devoted to the design of quantum-resistant and quantum-enhanced schemes, little effort has been made to understanding their physical security. Physical security deals with the design and implementation of security measures fulfilling the practical requirements of cryptographic primitives, which are equally essential for classic and quantum ones. This survey aims to draw greater attention to the importance of physical security, with a focus on secure key generation and storage as well as secure execution. More specifically, the possibility of performing side-channel analysis in the quantum world is discussed and compared to attacks launched in the classic world. Besides, proposals for quantum random number generation and quantum physically unclonable functions are compared to their classic counterparts and further analyzed to give a better understanding of their features, advantages, and shortcomings. Finally, seen from these three perspectives, this survey provides an outlook for future research in this direction.
