Abstract Physical Unclonable Functions (PUFs) or Physical One Way Functions (P-OWFs) are physical systems whose responses to input stimuli (i.e., challenges) are easy to measure (within reasonable error bounds) but hard to clone. This property of unclonability is due to the accepted hardness

and makes PUFs useful in solving problems such as authentication, software protection/licensing, and certified execution. In this abstract, we claim that any multi-core computer is usable as a timing-PUF and can be measured via simple benchmarking tools (i.e., no specialized hardware required). We

we propose new software obfuscation techniques, which are based on the difficulty of interprocedural analysis. The essence of our obfuscation techniques is a new complexity problem to precisely determine the address a function pointer points to in the presence of arrays of function pointers. We show

I begin by laying out a theoretical framework for the work in this area. This framework builds on models of marriage
