Physical Tamper Resistance
It is relatively easy to build an encryption system that is secure if it is working as intended and is used correctly but it is still very hard to build a system that does not compromise its security in situations in which it is either misused or one or more of its sub-components fails (or is ’encouraged’ to misbehave) . . . this is now the only area where the closed world is still a long way a...
متن کاملRevisiting Optical Physical Unclonable Functions
We revisit optical physical unclonable functions (PUFs), which were introduced by Pappu et al. [36, 37] in their seminal and historically first publication on PUFs. We start our studies with non-integrated PUFs. We discuss their resilience against machine learning attacks, and systematically study the influence of using more than one laser beam, varied laser diameters, and smaller scatterer siz...
متن کاملPhysical Attacks and Tamper Resistance
Many semiconductor chips used in a wide range of applications require protection against physical attacks or tamper resistance. These attacks assume that a direct access to the chip is possible with either establishing electrical connections to signal wires or at least doing some measurements. The importance of protection against physical attacks is dictated by the amount of valuable and sensit...
متن کاملNovel Reconfigurable Silicon Physical Unclonable Functions
Physical Unclonable Functions (PUFs) are novel circuit primitives which store secret keys in silicon circuits by exploiting uncontrollable randomness due to manufacturing process variations. Previous work has mainly focused on static challenge-response behaviors. However, it has already been shown that a reconfigurable architecture of PUF will not only enable PUFs to meet practical application ...
