Barak, Shaltiel Tromer showed how to construct a True Random Number Generator (TRNG) which is secure against an adversary who has some limited control over the environment. In this paper we improve the security analysis of this TRNG. Essentially, we significantly reduce the entropy loss and running time needed to obtain a required level of security and robustness. Our approach is based on repla...
Professor Goldwasser, together with Barak, Goldreich, and Lindell worked on Resettably-sound proofs and arguments. These concept was previously investigated by Reyzin and Micali in the public-key setting. These protocols maintain soundness even when the prover can reset the verifier to use the same random coins in repeated executions of the protocol. In the current work it is shown that resetta...
Extreme black holes with 1/8 of unbroken N = 8 supersymmetry are characterized by the non-vanishing area of the horizon. The central charge matrix has four generic eigenvalues. The area is proportional to the square root of the invariant quartic form of E7(7). It vanishes in all cases when 1/4 or 1/2 of supersymmetry is unbroken. The supergravity non-renormalization theorem for the area of the ...
In this paper we study one-round key-agreement protocols analogous to Merkle’s puzzles in the random oracle model. The players Alice and Bob are allowed to query a random permutation oracle n times and upon their queries and communication, they both output the same key with high probability. We prove that Eve can always break such a protocol by querying the oracle O(n) times. The long-time unpr...

Detailed information on the material covered during the semester, including relevant references to the literature, will be regularly given here. Our two main textbooks are listed below. Both of those textbooks are available for free download via the University of Vienna Library. The book of Herbert Enderton, Computability theory. An introduction to recursion theory , gives a detailed introducti...
Methods to automatically derive landforms have typically focused on pixel-based, bottom-up approaches and most commonly on the derivation of topographic eminences. In this paper we describe an object-based, top-down algorithm to identify valley floors. The algorithm is based on a region growing approach, seeded by thalwegs with pixels added to the region according to a threshold gradient value....
the use of temporary runoff and underground dried-up water courses has been implemented by managers in recentyears to compensate for water shortages in arid and semi-arid regions. one way to use this water is to set up anunderground sandy dam in front of such water courses; selecting a suitable water course is the most important issue ofsuch a purpose. in the present research, this matter was i...
This paper analyzes the three-dimensional flow structure and the heat budget in a typical medium-sized and steep Alpine valley, the Riviera Valley in southern Switzerland. Aircraft measurements from the MAP-Riviera field campaign reveal a very pronounced valley-wind system, including a strong curvature-induced secondary circulation in the southern valley entrance region. Accompanying radio soun...
