Two recently published papers propose some very simple key distribution schemes designed to enable two or more parties to establish a shared secret key with the aid of a third party. Unfortunately, as we show, most of the schemes are inherently insecure and all are incompletely specified - moreover, claims that the schemes are inherently lightweight are shown to be highly misleading. We also briefly critique a somewhat related very recent paper by the same authors that uses similar techniques to achieve what are claimed to be secure multiparty computations.

翻译：最近发表的两篇论文提出了一些非常简单的关键分配计划,旨在使两个或两个以上政党能够在第三方的帮助下建立共同的秘密钥匙。 不幸的是,正如我们所显示的那样,大多数计划本来就不安全,而且所有计划都未完全说明 — — 此外,声称计划本来就是轻便的,这证明具有高度误导性。 我们还简要批评了同一位作者最近发表的一份有点关联的论文,他们使用类似技术实现所谓的安全多党计算。
