Black-Box Models of Computation in Cryptology

Buy

Generic group algorithms solve computational problems defined over algebraic groups without exploiting properties of a particular representation of group elements. This is modeled by treating the group as a black-box. The fact that a computational problem cannot be solved by a reasonably restricted class of algorithms may be seen as support towards the conjecture that the problem is also hard in the classical Turing machine model. Moreover, a lower complexity bound for certain algorithms is a helpful insight for the search for cryptanalytic algorithms.

Tibor Jager addresses several fundamental questions concerning algebraic black-box models of computation: Are the generic group model and its variants a reasonable abstraction? What are the limitations of these models? Can we relax these models to bring them closer to the reality?

Adaptive Filtering and Change Detection
Adaptive Filtering and Change Detection

Adaptive filtering is a branch of digital signal processing which enables the selective enhancement of desired elements of a signal and the reduction of undesired elements. Change detection is another kind of adaptive filtering for non-stationary signals, and is the basic tool in fault detection and diagnosis.

Excel 2007: The Missing Manual
Excel 2007: The Missing Manual
Microsoft Excel continues to grow in power, sophistication, and capability, but one thing that has changed very little since the early '90s is its user interface. The once-simple toolbar has been packed with so many features over the years that few users know where to find them all. Microsoft has addressed this problem in Excel 2007 by radically...
