Abstract :
Physical Unclonable Functions are emerging cryptographic primitives used to implement low-cost device authentication and secure secret key generation. In this paper we propose an innovative design based on STT-MRAM memory. We exploit the high variability affecting the electrical resistance of the MTJ device in anti-parallel magnetization. We will show that the proposed solution is robust, unclonable and unpredictable.
