CRYPTO 2008 saw the introduction of the hash function MD6 and of cube attacks, a type of algebraic attack applicable to cryptographic functions having a low-degree algebraic normal form over GF(2). This paper applies cube attacks to reduced round MD6, finding the full 128-bit key of a 14-round MD6 with complexity 2 (which takes less than a minute on a single PC). This is the best key recovery a...
A new methodology named CALMANT (CC-cube Algorithms on Meshes and Tori) for mapping a kind of algorithms that we call CC-cube algorithm onto multicomputers with hypercube, mesh, or torus interconnection topology is proposed. This methodology is suitable when the initial problem can be expressed as a set of processes that communicate through a hypercube topology (a CC-cube algorithm). There are ...
Data cube queries containing aggregate functions often combine multiple tables through join operations. We can extend this to “Multi-Join Expansion_Aggregate” data cube queries by using more than one aggregate functions in “SELECT” statement in conjunction with relational operators. In parallel processing for such queries, it must be decided which attribute to use as a partitioning attribute, i...
Hierarchical phrase-based (Hiero) models have richer expressiveness than phrase-based models and have shown promising translation quality gains for many language pairs whose syntactic divergences, such as reordering, could be better captured. However, their expressiveness comes at a high computational cost in decoding, which is induced by huge dynamic programs associated with language model int...
Solutions calculated by Evolutionary Algorithms have come to surpass exact methods for solving various problems. The Rubik’s Cube multiobjective optimization problem is one such area. In this paper we design, benchmark and compare two different evolutionary approaches to solve the Rubik’s Cube. One is based on the work of Michael Herdy using predefined swapping and flipping algorithms, the othe...
Object tracking in video is vital for security surveillance, pattern and motion recognition, traffic control, augmented reality, human-computer interaction, etc. Despite the rapid growth of various techniques in recent years, certain technical challenges still exist in terms of efficiency, accuracy, and robustness. To ameliorate, this paper suggests a novel video object tracking approach by fir...
In this paper we propose a tangible cube as an input device for playfully changing between different TV-channels. First we consider several design approaches and compare them. Based on a cube that has embedded gravity sensing and wireless communication capabilities a prototype is implemented. A 3D graphical representation of the cube is shown on the television screen. On each face of the cube a...
Background and aims: One of the most common approach to understanding spatial and temporal trends of event data is to break it up into a series of time snapshots. Therefore space-time cube method applied in order to portray the likely trend in occurrence of the pulmonary tuberculosis (TB) cases. Methods: In this study, information of all patients with pul...
