摘要多方密码协议的安全性分析区分了两种协议
两种类型的对抗性设置：在非适应性设置下，被破坏的集合
在互动开始之前，各方都是事先选定的。在自适应设置中
对手选择在计算过程中破坏谁。我们学习
自适应安全(即在自适应环境中的安全)与非自适应之间的关系
安全，根据两个定义和几个计算模型。
AbstractSecurity analysis of multi-party cryptographic protocols distinguishes between
two types of adversarial settings: In the non-adaptive setting the set of corrupted
parties is chosen in advance, before the interaction begins. In the adaptive setting the
adversary chooses who to corrupt during the course of the computation. We study
the relations between adaptive security (i.e., security in the adaptive setting) and nonadaptive
security, according to two definitions and in several models of computation.
