摘要

为了应对量子计算机带来的威胁，Pilaram和Eghlidos提出了第一个基于晶格的多级秘密共享方案，这是唯一的后量子多级秘密共享机制。在本文中，我们介绍了一种对它的有效攻击，并表明任何对手只要收集到足够的伪秘密共享，都可以很容易地重建未恢复的秘密。为了完整起见，我们进一步列出了两种保护方案免受此类攻击的对策。

On the Security of a Lattice-Based Multi-Stage Secret Sharing Scheme

In response to the threat posed by quantum computers, Pilaram and Eghlidos proposed the first lattice-based multi-stage secret sharing scheme which is the only post-quantum multi-stage secret sharing scheme. In this paper, we introduce an efficient attack on it and show that any adversary can easily reconstruct unrecovered secrets as long as it collects enough pseudo-secret shares. For the sake of complete, we further list two countermeasures to protect the scheme from such attack.
