Combined Modeling and Side Channel Attacks on Strong PUFs
Physical Unclonable Functions (PUFs) have established themselves in the scientific literature, and are also gaining ground in commercial applications. Recently, however, several attacks on PUF core properties have been reported. They concern their physical and digital unclonability, as well as their assumed resilience against invasive or side channel attacks. In this paper, we join some of thes...
متن کاملOn the Security of PUF Protocols under Bad PUFs and PUFs-inside-PUFs Attacks
We continue investigations on the use of so-called Strong PUFs as a cryptographic primitive in realistic attack models, in particular in the “Bad/Malicious PUF Model”. We obtain the following results: – Bad PUFs and Simplification: As a minor contribution, we simplify a recent OT-protocol for malicious PUFs by Dachman-Soled et al. [4] from CRYPTO 2014. We can achieve the same security propertie...
متن کاملOn the effects of combining objectives in multi-objective optimization
In multi-objective optimization, one considers optimization problems with more than one objective function, and in general these objectives conflict each other. As the solution set of a multiobjective problem is often rather large and contains points of no interest to the decision-maker, strategies are sought that reduce the size of the solution set. One such strategy is to combine several obje...
متن کاملOn the Scaling of Machine Learning Attacks on PUFs with Application to Noise Bifurcation
Physical Unclonable Functions (PUFs) are seen as a promising alternative to traditional cryptographic algorithms for secure and lightweight device authentication. However, most strong PUF proposals can be attacked using machine learning algorithms in which a precise software model of the PUF is determined. One of the most popular strong PUFs is the XOR Arbiter PUF. In this paper we examine the ...
متن کاملLow-temperature data remanence attacks against SRAM PUFs
In this paper, we present the first systematic investigation of data remanence effects on an intrinsic Static Random Access Memory Physical Unclonable Function (SRAM PUF) implemented on a commercial off-the-shelf (COTS) device in a temperature range between -110◦ C and -40◦ C. Although previous studies investigated data remanence in SRAMs only at temperatures above -50◦ C, our experimental resu...
