Circuits for security

Abstract

Internet of things (IOT) usage has been on the rise and will continue to increase as technology improves. This gives rise to a need for better security for the vulnerable IOT. Physical unclonable function (PUF) is one of the techniques that are being used to provide security and SRAM PUF is one of the preferred type of PUF. While being a storage memory, it can simultaneously be used as part of a security system without requiring additional component on the device. Effect of process, voltage and temperature (PVT) on SRAM PUF will be studied and novel idea(s) will be proposed to counter the effect that can degrade the SRAM PUF reliability.
