Abstract

We consider a notion of non-interference for timed automata (TAs) that allows to quantify the frequency of an attack; that is, we infer values of the minimal time between two consecutive actions of the attacker, so that (s)he disturbs the set of reachable locations. We also synthesize valuations for the timing constants of the TA (seen as parameters) guaranteeing non-interference. We show that this can reduce to reachability synthesis in parametric timed automata. We apply our method to a model of the Fischer mutual exclusion protocol and obtain preliminary results.
时间自动机的参数不干涉
我们考虑了时间自动机(TAs)的非干扰概念,该概念允许量化攻击的频率;也就是说,我们推断攻击者的两个连续动作之间的最小时间值,这样他就扰乱了可达位置集。我们还综合了TA的定时常数(作为参数)的估值,以保证不受干扰。我们证明了这可以简化为参数时间自动机的可达性综合。我们将该方法应用于一个Fischer互斥协议模型,并得到了初步结果。
