We study the small-scale topology of dynamical phenomena in the quiet-sun internetwork atmosphere, using short-duration Fourier analysis of high-resolution filtergram sequences to obtain statistical estimates for the co-location probability of different fine-structure elements and wave modes. In this initial paper we concentrate on the topology of shortduration Fourier amplitude maps for the ph...

Traffic analysis is a type of attack on secure communications systems, in which the adversary extracts useful patterns and information from the observed traffic. This paper improves and extends an efficient traffic analysis attack, called “statistical disclosure attack.” Moreover, we propose a solution to defend against the improved (and, a fortiori, the original) statistical disclosure attack....

BACKGROUND There will be increasing pressure to publicly report and rank the performance of healthcare systems on human immunodeficiency virus (HIV) quality measures. To inform discussion of public reporting, we evaluated the influence of case-mix adjustment when ranking individual care systems on the viral control quality measure. METHODS We used data from the Veterans Health Administration ...

This paper addresses the security and efficiency issues of the Mix-net based on permutation networks introduced in [1]. We first show that the original construction results in a Mix-net that yields biased permutation, so it gives some advantage to adversaries. A simple repair is provided. We then observe that one of the original schemes can be improved so that the servers and verifier enjoy mor...

We present the architecture, design issues and functions of a MIX-based system for anonymous and unobservable real-time Internet access. This system prevents tra c analysis as well as ooding attacks. The core technologies include an adaptive, anonymous, time/volumesliced channel mechanism and a ticket-based authentication mechanism. The system also provides an interface to inform anonymous user...
