In this paper, we present theory of the finite state machine to describe the Honey Pot System model and simulate the process of capturing the attack action upon finite state machine state transition diagram to provide the theoretical method and reasoning for designing and deploying of it. 本文通过确定性有限自动机理论对蜜罐系统模型进行描述,根据确定性有限自动机状态转换图模拟捕捉攻击行为的全过程,为密罐系统的设计和部署提供有力的理论依据和论证。
