简介：知识产权(IP)保护是在硬件安全的顶级问题之一。半导体工业仍然缺乏有效、积极的防卫从基于的工程(RE)攻击的颠倒防护IP。集成电路(IC)camouflaging技术由没有改变IP的功能，用特殊设计的逻辑房间(叫的camouflaged门)在IP代替一些常规逻辑门充满这差距。当维持相同的看到RE攻击者时，camouflaged门能执行不同逻辑功能，因此阻止他们从RE工具直接获得IP的布局信息。因为它首先在2012被建议，电路camouflaging在硬件安全集中于二个基本问题成为了最热的研究话题之一。怎么选择camouflaged门的类型并且决定在哪儿插入他们以便同时最小化性能开销并且优化RE复杂性？怎么装攻击者de伪装一个camouflaged电路并且完成RE攻击？在这篇文章，我们通过这根矛和盾种族考察电路camouflaging的进化。首先，我们基于true/dummy接触介绍camouflaged房间的四种不同类型的设计方法，静态的随机的存取记忆(静态存储器)，做，并且新兴的设备分别地。然后，我们详细描述四代表性的伪装de攻击：蛮力攻击，测试的IC基于攻击，基于可满足性(坐基于)攻击，和电路分区基于攻击，和相应反措施：基于派系的camouflaging，CamoPerturb，并且树camouflaging，和相等的班分别地基于camouflaging。我们主张当前的研究努力应该在减少电路camouflaging介绍的开销并且打败伪装de攻击上。我们指出探索新兴的设备的特征能是一个有希望的方向。作为到电路camouflaging的补充，最后，我们与另外的最先进的IP保护技术的简短评论得出结论。
