IIT Kgp develops solution to check hacking into IoT devices

Researchers at the institute used routine sniffers (programme/device that monitors data traveling over a network) to attack a video the Wi-Fi camera was streaming and transferring to a PC, by first spoofing the IP of the camera and then injecting its own videos. “The PC starts recording a wrong streaming file, which can be utilised by the attacker in several ways,” said Debdeep Mukhopadhyay, computer science professor at IIT Kharagpur.

“Our solution binds a unique PUF (physically unclonable functions)-based identity to the Wi-Fi camera,” he said. “As the attacker does not have any knowledge of the PUF solution (which cannot be cloned), it cannot communicate with the receiver PC.

In simple terms, no device (without PUF) can communicate with the PC and this stops the attack.” This is crucial as IoT has already led to billions of connected devices and gradually all new devices are expected to be IoT-enabled.
