Mohassel &富兰克林(PKC 2006)的双执行协议是一个高效的(每一方只混淆一个电路)2PC协议,除了泄漏一个任意的,敌对选择的关于诚实方的输入谓词之外,它还实现了恶意的安全性。我们提出了两个实用和正交的方法来提高双执行技术的安全性。
The dual-execution protocol of Mohassel & Franklin (PKC 2006) is a highly efficient (each party garbling only one circuit) 2PC protocol that achieves malicious security apart from leaking an arbitrary, adversarially-chosen predicate about the honest party’s input. We present two practical and orthogonal approaches to improve the security of the dual-execution technique.
