A common assumption in security research is that more individual expertise unambiguously leads to a more secure overall network. We present a game-theoretic model in which this common assumption is challenged. Our findings indicate that expert users can be not only invaluable contributors, but also free-riders, defectors, and narcissistic opportunists. A direct application is that user educatio...

A common assumption in security research is that more individual expertise unambiguously leads to a more secure overall network. We present a game-theoretic model in which this common assumption does not hold.

Component fault trees that contain safety basic events as well as security basic events cannot be analyzed like normal CFTs. Safety basic events are rated with probabilities in an interval [0,1], for security basic events simpler scales such as {low, medium, high} make more sense. In this paper an approach is described how to handle a quantitative safety analysis with different rating schemes f...

This paper shows that the security of blind signatures is, as defined by Juels, Luby and Ostrovsky, truly weaker than the security in the universal composability (UC) framework (i.e., define the ideal functionality of blind signatures), which was introduced by Canetti. That is, we formulate the security of blind signatures in the UC framework, and show that the class of UC-secure blind signatur...

The security of computation at the level of a specific programming language and the security of complex systems at a more abstract level are two major areas of current security research. With the objective to integrate the two, this article proposes a translation of a timing-sensitive security property for simple multi-threaded programs into a more general security framework. Interestingly, our...
