5. The following problems are based on the following paper that we discussed in class: C. Lamech, R. M. Rad, M. Tehranipoor, and J. Plusquellic, "An Experimental Analysis of Power and

Delay Signal-to-Noise Requirements for Detecting Trojans and Methods for Achieving the Required Detection Sensitivities," Information Forensics and Security, IEEE Transactions on DOI - 10.1109/TIFS.2011.2136339, vol. 6, no. 3, pp. 1170-1179, 2011. Consider the following frequency data (in GHz) collected for 10 different ring oscillators on 8 different chips. (An excel spreadsheet with the same data is also available in the homework folder for you to download.)
