Physically Related Functions: A New Paradigm for Light-weight Key-Exchange
Durba Chatterjee and Harishma Boyapally and Sikhar Patranabis and Urbi Chatterjee and Debdeep Mukhopadhyay and Aritra Hazra
Abstract
In this paper, we propose a novel primitive named Physically Related Function (PReF) which are devices with hardware roots of trust. It enables secure key-exchange with no pre-established/embedded secret keys. This work is motivated by the need to perform key-exchange between lightweight resource-constrained devices. We present a proof-of-concept realization of our contributions in hardware using FPGAs.
