Abstract
Hardware Intrinsic Security (HIS) is currently a very crucial aspect of the electronics industry aimed towards protecting hardware IPs from infringement. Also, Wireless Sensor Nodes (WSNs) that are increasingly acting as a backbone to the information channels need a secure and low-power encryption system to protect them from malicious attacks. Traditional electronic devices store encrypted keys in battery-powered volatile memories or use Non-Volatile Memories for permanent storage of security keys. These are not very secure since the security key is exposed and relatively easy to hack from Non-Volatile Memory (NVM). Additionally, it comparatively consumes more power for operating over a long period of time. Thus, SRAM-PUF can provide a viable solution to both the problems - secure encryption & minimal power consumption.
