Fingerprinting of Digital Devices

Aim of this project is to fingerprint the digital devices based on the unique characteristics in the transmitted signal. In theory, it has been demonstrated that every electrical device imparts specific pattern of the noise in the physical signal to be transmitted. This specif noise pattern can be used to link the transmitted signal to its transmitter and even the channel.

Below figure demonstrates the uniqueness of the channel even if the transmitter of the signals is same, change of transmitter results in the change in physical signal pattern.

We are using this property in order to develop an Intrusion Detection System (IDS) for the CAN Bus networks where the traditional cryptographic solutions of authentication are inefficient. The nodes in the network are fingerprinted based on the respective physical signal characteristics. We are investigating different techniques to oberve this uniqueness for both transmitter as well as the channel and the studying the environment impact.
