On the entropy of Physically Unclonable Functions
2016 IEEE International Symposium on Information Theory (ISIT), 2016A physically unclonable function (PUF) is a hardware device that can generate intrinsic responses from challenges. The responses serve as unique identifiers and it is required that they be as little predictable as possible. A loop-PUF is an architecture where n single-bit delay elements are chained. Each PUF generates one bit response per challenge. We

Muscular strength and physical function
Medicine & Science in Sports & Exercise, 2000The purpose of this study was to evaluate the potential association of muscular strength and endurance at baseline with the prevalence of functional limitations at follow-up.Study participants were 3,069 men and 589 women (30-82 yr) who received a clinical examination including a strength evaluation at the Cooper Clinic between 1980 and 1989 and ...

On the physical security of physically unclonable functions
2017Reconfigurable hardware is the primary component of electronic embedded devices employed in several applications ranging from wireless communication to cloud computing. Due to their significant role these modern platforms are targets of intellectual property (IP) piracy and tampering. Cloning of a design or manipulation of its content is carried out by

Assessing Physical Function in the Elderly
Clinics in Geriatric Medicine, 1987This article emphasizes the complexity underlying the assessment of physical function. The concept of physical function is multidimensional; individuals or groups can be assessed; the assessments can be either preintervention measures or outcome measures. Six issues of measurement are discussed: verbal report versus behavior; self-reported versus proxy-

Physical properties and function of phallolysin
Biochemistry, 1983Phallolysin, a mixture of two to three cytolytic proteins (all of Mr 34 000), has been isolated from Amanita phalloides mushrooms and purified to homogeneity (specific activity 24 000 hemolytic units/mg of protein). After separation by isoelectric focusing, the amino acid composition of two of these proteins has been determined.

Cloning Physically Unclonable Functions
2013 IEEE International Symposium on Hardware-Oriented Security and Trust (HOST), 2013As system security demands continue to evolve, Physically Unclonable Functions (PUFs) are a promising solution for secure storage on Integrated Circuits (ICs). SRAM PUFs are among the most popular types of PUFs, since they require no additional circuitry and can be implemented with on-die memories such as caches and data memory that are readily ...

The physical aspects of enzyme functioning
Journal of Theoretical Biology, 1976The discussion of the thermodynamics and kinetics of protein reactions leads to the conclusion, that for the proteins postulates determining the applicability of Vant'-Hoff and Arrhenins equations are as a rule not fulfilled. It can be explained by the fact that proteins are kinetically unequilibrated structures with rigid memory on various ...

Sensor physical unclonable functions
2010 IEEE International Symposium on Hardware-Oriented Security and Trust (HOST), 2010We propose a novel variety of sensor that extends the functionality of conventional physical unclonable functions to provide authentication, unclonability, and verification of a sensed value. This new class of device addresses the vulnerability in typical sensing systems whereby an attacker can spoof measurements by interfering with the analog signals ...

Distribution functions in physics: Fundamentals
Physics Reports, 1984This is the first part of what will be a two-part review of distribution functions in physics. Here we deal with fundamentals and the second part will deal with applications. We discuss in detail the properties of the distribution function defined earlier by one of us (EPW) and we derive some new results.
