Temperature-Based Physical Unclonable Function for Secret Key Generation
نویسندگان
چکیده
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 digital emulation.

A Formal Definition and a New Security Mechanism of Physical Unclonable Functions
The characteristic novelty of what is generally meant by a “physical unclonable function” (PUF) is precisely defined, in order to supply a firm basis for security evaluations and the proposal of new security mechanisms. A PUF is defined as a hardware device which implements a physical function with an output value that changes with its argument. A PUF can be clonable, but a secure PUF must be u...

Physical Unclonable Function (PUF) is the hardware analog of a one-way function which can address hardware security issues such as device authentication, generating secret keys, producing seeds for Random Number Generators, etc. Traditional silicon PUFs are based on delay (Ring Oscillator PUFs and Arbiter PUFs) or memory structures (e.g, SRAM PUFs). In this paper, we propose the design of an ag...
متن کاملUsing Power-Up SRAM State of Atmel ATmega1284P Microcontrollers as Physical Unclonable Function for Key Generation and Chip Identification
Secret keys are usually stored in an nonvolatile memory, which can be hard to secure. An alternative is to generate the keys “on-the-fly” by using the inherent uniqueness of a device based on the manufacturing process variations. This is realized by physical unclonable functions (PUFs). A promising approach is to construct an intrinsic PUF based on SRAM memory, since many electronic devices hav...

متن کاملOptimal SVD-based Precoding for Secret Key Extraction from Correlated OFDM Sub-Channels
Secret key extraction is a crucial issue in physical layer security and a less complex and, at the same time, a more robust scheme for the next generation of 5G and beyond. Unlike previous works on this topic, in which Orthogonal Frequency Division Multiplexing (OFDM) sub-channels were considered to be independent, the effect of correlation between sub-channels on the secret key rate is address...
