    • A Ring Oscillator Based Truly Random Number Generator 

      Robson, Stewart (University of Waterloo, 2013-09-25)
      Communication security is a very important part of modern life. A crucial aspect of security is the ability to identify with near 100% certainty who is on the other side of a connection. This problem can be overcome through ...
    • Risk Minimization in Power System Expansion and Power Pool Electricity Markets 

      Alvarez Lopez, Juan (University of Waterloo, 2007-12-21)
      Centralized power system planning covers time windows that range from ten to thirty years. Consequently, it is the longest and most uncertain part of power system economics. One of the challenges that power system ...
    • An RNS variant of fully homomorphic encryption over integers 

      Zawia, Ahmed (University of Waterloo, 2017-05-01)
      In 1978, the concept of privacy homomorphism was introduced by Rivest et al. Since then, homomorphic cryptosystems have gathered researchers' attention. Most of the early schemes were either partially homomorphic or not ...
