Modeling attack resistant strong PUF circuit

The invention discloses a strong PUF circuit resistant to modeling attack, and belongs to the technical field of basic electronic circuits. The strong PUF circuit is an input one-output circuit and comprises an input confusion component, an insertion bit generation component and a strong PUF component, bit excitation is applied to the input end of the input confusion component, the bit output of the confusion component is subjected to XOR operation to generate an insertion bit, and the insertion bit and the output of the confusion component jointly form the bit excitation to be applied to the strong PUF component. And the strong PUF component generates one-bit output, so that the aim of resisting the attack of the existing strong modeling is fulfilled on the basis of keeping lightweight. 本发明公开一种抗建模攻击的强PUF电路，属于基本电子电路的技术领域。该强PUF电路是一个输入1输出电路，包括：输入混淆组件、插入位生成组件和强PUF组件，位激励施加在输入混淆组件的输入端，混淆组件的位输出进行异或运算产生插入位，插入位和混淆组件的输出共同组成位激励施加在强PUF组件上，强PUF组件产生一位输出，在保持轻量级的基础上实现抵抗现有强效建模攻击的发明目的。
