Low-power sub-threshold design of secure physical unclonable functions

TL;DR: This work optimize the PUF supply voltage for the minimum power-delay product and investigates the trade-offs on PUF uniqueness and reliability and demonstrates that such a design optimization does not compromise the security of PUFs regarding modeling attacks and side-channel analysis attacks.
Journal ArticleDOI

Cache-Centric Video Recommendation: An Approach to Improve the Efficiency of YouTube Caches

TL;DR: This article takes advantage of the user behavior of requesting videos from the top of the related list provided by YouTube to improve the performance of YouTube caches and recommends that local caches reorder the related lists associated with YouTube videos, presenting the cached content above noncached content.
Book ChapterDOI

On the feasibility of prefetching and caching for online TV services: a measurement study on hulu

TL;DR: This paper investigates the advantages of using a prefetching scheme where the most popular videos of the week, as provided by the hulu website, are prefetched and compares this approach with a conventional LRU caching scheme with limited storage space and a combined scheme ofPrefetching and caching.
Journal ArticleDOI

Design and Validation of Arbiter-Based PUFs for Sub-45-nm Low-Power Security Applications

TL;DR: A Monte Carlo-based statistical analysis has demonstrated that advanced technologies and reduced supply voltage can improve the PUF uniqueness due to increased delay sensitivity and postsilicon validation on arbiter-based PUF test chips in 45 nm SOICMOS technology has been correlated to simulation results and the inconsistency has been discussed.
Proceedings ArticleDOI

DASHing YouTube: An analysis of using DASH in YouTube video service

TL;DR: An analysis on the advantages and disadvantages of using DASH as YouTube's video streaming format and the potential reduction in bandwidth consumption by employing DASH in YouTube, based on user watching patterns is presented.
