+ MPW8 : ARBITER PUF
+ 
+Arbiter PUFs. utilize the intrinsic timing differences of two symmetrically designed paths to a. single bit of the response at the output of the circuit 
 
-## Please fill in your project documentation in this README.md file 
+Arbiter-based Physically Unclonable Function (PUF) is one kind of the delay-based PUFs that use the time difference of two delay-line signals.

-Refer to [README](docs/source/index.rst) for this sample project documentation. 
+In cryptography and within embedded security ICs, the PUF is used to create keys that are generated on-demand and instantaneously erased once used. PUF is dependent on random physical factors (unpredictable and uncontrollable) that exist natively and/or are incidentally introduced during a manufacturing process.
