Obtaining probabilistic judgments from subject-matter experts is a difficult task, especially when those experts are not quantitatively trained. In this paper, we introduce a simple elicitation process where intelligence experts express their knowledge about adversary preferences by rank ordering the attractiveness of a collection of possible terrorist targets (or attack strategies), where the ...

Motivated by the effectiveness of correlation attacks against Tor, the censorship arms race, and observations of malicious relays in Tor, we propose that Tor users capture their trust in network elements using probability distributions over the sets of elements observed by network adversaries. We present a modular system that allows users to efficiently and conveniently create such distribution...

The expert witness testifies under oath to tell "the whole truth," yet certain aspects of the legal system itself make this ideal difficult or impossible. The authors present both a philosophical and a practical discussion of the challenges for the expert in attaining this goal. After review of oaths in general and truth-telling in particular, real-life examples are provided to examine the vici...

Password-based remote authentication schemes provide users with convenient and secure mechanisms to access resources through networks. Such schemes can be further divided into static ID and dynamic ID schemes. The main drawback of the static ID scheme is that an adversary can intercept the fixed login ID and masquerade as a legal user to log into the system. On the other hand, dynamic ID scheme...

The outcome of a legal dispute, namely, the decision of its adjudicator, is uncertain, and both parties develop their strategies on the basis of their appreciation of the probability that the adjudicator will accept their arguments or the arguments of their adversary. Costs and gains have to be balanced in light of this uncertainty in order to identify the most convenient strategies. This paper...
