Securing home networks using Physically Unclonable Functions

We propose techniques to secure smart homes using Physically Unclonable Functions (PUF). Physically Unclonable functions are objects which are unclonable and provide only one response when a challenge is presented. These are tamper-proof and cannot be manipulated without physically destroying them. Thus, they are alternatives to smart cards and biometric devices which are being used to secure home networks. We address three problems in this paper: user authentication, device-to-device authentication and protection of intellectual property using PUF. To the best of our knowledge this is the first application of PUF in securing home networks.
