Physical One-Way Functions [PDF]

open access: yesScience, 2002
Modern cryptographic practice rests on the use of one-way functions, which are easy to evaluate but difficult to invert. Unfortunately, commonly used one-way functions are either based on unproven conjectures or have known vulnerabilities. We show that instead of relying on number theory, the mesoscopic physics of coherent transport through a ...

Controlled Physical Random Functions [PDF]

open access: yes18th Annual Computer Security Applications Conference, 2002. Proceedings., 2003
A physical random function (PUF) is a random function that can only be evaluated with the help of a complex physical system. We introduce controlled physical random functions (CPUFs) which are PUFs that can only be accessed via an algorithm that is physically bound to the PUF in an inseparable way. CPUFs can be used to establish a shared secret between

Measuring Pediatric Physical Function [PDF]

open access: yesJournal of Pediatric Orthopaedics, 1995
Most pediatric orthopaedic interventions are intended to improve or preserve physical function, yet their outcomes have been assessed using primarily surrogate measures (e.g., radiographic indices) that may not accurately represent patients' function. Physical function may be more appropriately measured with activity-based scales, but these have been ...
