Scientists at IIT- Kharagpur Develops Prototype for IoT security

The Internet of Things (IoT) is moving from a centralized structure to a complex network of decentralized smart devices. This shift promises entirely new services and business opportunities. But, as it made from many different semiconductor technologies, including power management devices, sensors, and microprocessors IoT security has quickly escalated as a hot-button issue.

So, to enhance the IoT security, scientists from Indian Institute Of Technology (IIT)– Kharagpur have developed fingerprint generator circuits. The circuits are also called as Physically Unclonable Functions’ (PUF).

Generally, IoT devices run on a command being sent out from one device to another through a network, and these commands are often unencrypted. This makes electronic devices vulnerable to hacking and manipulations in command.

Rajat Subhra Chakraborty of IIT- Kgp said, “The PUFs consume very less power and are light weight, hence can be installed in any IoT device. PUFs are fingerprint generator circuits for electronic objects which uniquely identify each object, and help in authenticating the commands sent to connected IoT devices.”

This IoT security device could read the command, verify the authenticity of the sender and then operate. Scientists are now testing it on commercially available devices at the IoT Lab.

Research scholar Urbi Chatterjee said, “Testing has been successfully completed for the wireless smart lighting system and wireless IP CCTV camera. The team equipped the devices with PUF and tested them for unauthorized usage which was prevented through PUF.”
