Most present symmetric encryption algorithms result from a tradeoff between implementation cost and resulting performances. In addition, they generally aim to be implemented efficiently on a large variety of platforms. In this paper, we take an opposite approach and consider a context where we have very limited processing resources and throughput(More)
Quantum computation remains an enormously appealing but elusive goal. It is appealing because of its potential to perform superfast algorithms, such as finding prime factors in polynomial time, but also elusive because of the difficulty of simultaneously manipulating quantum degrees of freedom while preventing environmentally induced decoherence. A new(More)
system to date has served all of the needs of wearable computing—light weight, minimum effort, high power generation, convenient power delivery, and good power regulation. We believe that our approach has the potential to solve these problems for a class of wearable devices by placing both the generator and powered electronics in a location where(More)
A non-contact sensor based on the interaction of a person with electric fields for human-computer interface is investigated. Two sensing modes are explored: an external electric field shunted to ground through a human body, and an external electric field transmitted through a human body to stationary receivers. The sensors are low power (milliwatts), high(More)
