Physically Unclonable Functions, design, evaluation and application

Dr Basel Halak, National Teaching Fellow and Fellow of the Royal Academy of Engineering, presents an in depth tutorial on the implementation of Physically Unclonable Functions and their applications in security of hardware devices.

The 50 minute tutorial covers the principles of physical disorder that realises Physically Unclonable Functions (PUF) and the variety of circuit designs that capture this phenomena to deliver the variability they need. It presents quality metrics that can be used to evaluate a PUFs performance with regards to parameters such as uniqueness, reliability. etc.  

The tutorial then covers a variety of applications of PUFs in hardware security and the limitation of PUF solutions considering the forms of attacks and adversaries.  Finally the tutorial covers some of the remaining outstanding challenges and the emerging solutions that are being considered.
