非交互式零知识（NIZK）方案的两个标准安全性质是可靠性和零知识。但是，虽然标准的NIZK系统只能提供这些属性之一，对无界的对手，双模式NIZK系统允许动态和自适应地选择这些属性中的哪一个保持无条件。唯一已知的双模NIZK方案是Groth-Sahai证明（已证明在各种应用中非常有用），以及Canetti等人和Peikert等人的基于FHE的NIZK构造，它们与这项工作并行且独立。然而，所有这些构造都依赖于特定的代数设置。
Two standard security properties of a non-interactive zero-knowledge (NIZK) scheme are soundness and zero-knowledge. But while standard NIZK systems can only provide one of those properties against unbounded adversaries, dual-mode NIZK systems allow to choose dynamically and adaptively which of these properties holds unconditionally. The only known dual-mode NIZK schemes are Groth-Sahai proofs (which have proved extremely useful in a variety of applications), and the FHE-based NIZK constructions of Canetti et al. and Peikert et al, which are concurrent and independent to this work. However, all these constructions rely on specific algebraic settings.
