We prove in a non-black-box way that every bounded list and set commitment scheme is knowledge-binding. This is a new and rather strong security condition, which makes the security definitions for time-stamping much more natural compared to the previous definitions, which assume unpredictability of adversaries. As a direct consequence, list and set commitment schemes with partial opening proper...

We show that the unrestricted black-box complexity of the n-dimensional XORand permutation-invariant LeadingOnes function class is O(n log(n)/ log logn). This shows that the recent natural looking O(n logn) bound is not tight. The black-box optimization algorithm leading to this bound can be implemented in a way that only 3-ary unbiased variation operators are used. Hence our bound is also vali...

Constrained objects provide a suitable object-oriented style for modeling systems under constraints. A set of classes is defined to represent a problem, whose state is then controlled by a constraint satisfaction engine. This engine is commonly a black-box based on a predefined and non-customizable search strategy. This system rigidity, of course, does not allow users to tune models in order to...

Efficient and thorough testing is essential to create quality software. In some cases, software code may not be available in testing phase. In such scenarios black box testing is used. The work presents various black box testing techniques. A systematic literature review has been carried out according to the guidelines proposed by kitchenham. The work discusses the applicability of artificial i...

This practice will identify and prioritize the software attributes. Attributes are the quality characteristics of the software being tested. They are independent of the functional aspects, and primarily relate to the architectural structural aspects of a system. Attribute testing is complex and often avoided because it requires innovative testing techniques. However, many of the dissatisfaction...

Testentwurfsverfahren werden in die beiden Kategorien White-Box und Black-Box eingeteilt. Die Black-Box-Verfahren setzen auf der Spezifikation auf, um daraus systematisch Testfälle abzuleiten. Die White-Box-Verfahren nutzen hierfür zusätzlich den Programmtext. Oft werden beide als gleichwertig angesehen, wobei die White-BoxVerfahren eher auf den unteren Teststufen (Komponentenund Integrationste...
