【摘要】：物理不可克隆函數(shù)(physical unclonable function,PUF)在信息安全領域的應用日益廣泛.然而,仲裁型PUF作為一種典型的強PUF,因邏輯確定而易被建模攻擊破解;弱PUF雖然對建模攻擊免疫,但無法提供較多激勵響應對.為解決此問題,提出了一種非確定性仲裁型PUF,通過結合仲裁型PUF和弱PUF,使非確定性仲裁型PUF的部分布爾邏輯關系取決于弱PUF的不確定性輸出,以提高該PUF的邏輯不確定性,進而提高了其抗建模攻擊能力.同時,在FPGA上的實驗也表明,所提設計具有較高的隨機性(50.6%)和穩(wěn)定性(94.5%).
[Abstract]:Physical non-clonal function (physical unclonable functionPUF) is widely used in the field of information security. However, as a typical strong PUFF, arbitration PUF is easy to be cracked by modeling attack because of logic determination, and weak PUF is immune to modeling attack, but it can not provide more incentive response pairs. In order to solve this problem, a non-deterministic arbitration type PUFs is proposed. By combining the arbitration PUF and weak PUFs, the partial Boolean logic relationship of the non-deterministic arbitration PUF depends on the uncertain output of the weak PUF, so as to improve the logic uncertainty of the PUF. Furthermore, the ability of resisting modeling attack is improved. At the same time, the experiments on FPGA show that the proposed design has high randomness (50.6%) and stability (94.5%).
