A Research on New Physical Unclonable Functions in Smart Home

The lack of robust tamper-proofing techniques in security applications has provided attackers the ability to virtually circumvent mathematically strong cryptographic primitives by directly attacking the hardware. The paper proposed a simple method to measure resistance variations in the Power Distribution System( PDS) of an IC,and described how these measurements can be applied to a Physical Unclonable Function( PUF). Our technique exploits the PDS.
