In contrast to the enormous advances made in cryptographic technology over the last 40 years, there have been correspondingly few advances in anonymizing channels. This lag in advances is due the technical challenge of constructing a provably secure, yet practical, solution to the problem. While practical approaches, such as the widely used Tor network, have not been proven to be secure; provab...

Gossiping has been identified as a useful building block for the development of large-scale, decentralized collaborative systems. With gossiping, individual nodes periodically interact with random partners, exchanging information about their local state; yet, they may globally provide several useful services, such as information diffusion, topology management, monitoring, load-balancing, etc. O...

The retail market for electric power does not exhibit the usual behavior of supply and demand. Strict regulation on utility companies restrict the prices consumers can be charged. Allowing the companies to vary the price can afford them the opportunity to pass costs along to the consumers and perhaps help avoid catastrophes such as the California electric crisis. In this paper we analyze a syst...
