Barrel Shifter Physical Unclonable Function Based Encryption
Physical Unclonable Functions (PUFs) are circuits designed to extract physical randomness from the underlying circuit. This randomness depends on the manufacturing process. It differs for each device enabling chip-level authentication and key generation [1] applications. We present a protocol utilizing a PUF for secure data transmission. Parties each have a PUF used for encryption and decryptio...
متن کاملmrPUF: A Novel Memristive Device Based Physical Unclonable Function
Physical unclonable functions (PUFs) exploit the intrinsic complexity and irreproducibility of physical systems to generate secret information. They have been proposed to provide higher level security as a hardware security primitive. PUFs are an emerging and promising solution for establishing trust in an embedded system with low overhead with respect to energy and area. Most current PUF desig...
متن کاملmrPUF: A Memristive Device based Physical Unclonable Function
Physical unclonable functions (PUFs) exploit the intrinsic complexity and irreproducibility of physical systems to generate secret information. PUFs have the potential to provide fundamentally higher security than traditional cryptographic methods by preventing the cloning of identities and the extraction of secret keys. One unique and exciting opportunity is that of using the super-high inform...
متن کاملPhysical Unclonable Function (PUF) Based Random Number Generator
Physical Unclonable Functions (PUFs) are widely used to generate random Numbers. In this paper we propose a new architecture in which an Arbiter Based PUF has been employed as a nonlinear function in Nonlinear Feedback Shift Register (NFSR) to generate true random numbers. The rate of producing the output bit streams is 10 million bits per second. The proposed RNG is able to pass all NIST tests...
متن کاملTemperature-Based Physical Unclonable Function for Secret Key Generation
Because the PUF taps into the random variation during an IC fabrication process, the secret is extremely difficult to predict or extract and thus in terms of five following characteristics they are more powerful than RFIDs: 1) Unpredictability 2) Resiliency against reverse engineering 3) Stability against voltage variations 4) stability against imperfection of arbiters 5) Resiliency against dig...
