Contradiction Immunity and Guess-Then-Determine Attacks on Gost
ABSTRACT GOST is a well-known government standard cipher. Since 2011 several academic attacks on GOST have been found. Most of these attacks start by a so called “Complexity Reduction” step [CourtoisExpand

Combined algebraic and truncated differential cryptanalysis on reduced-round SIMON
Recently, two families of ultra-lightweight block ciphers were proposed, SIMON and SPECK, which come in a variety of block and key sizes (Beaulieu et al., 2013). They are designed to offer excellentExpand

Can GOST Be Made Secure Against Differential Cryptanalysis?
Abstract GOST is a well-known Russian government standard block cipher which was submitted to ISO in 2010 to become an international standard. A number of advanced differential attacks on GOST haveExpand

Leaf Caloric Value from Tropical to Cold-Temperate Forests: Latitudinal Patterns and Linkage to Productivity
Leaf caloric value (LCV) reflects the capacity of a leaf to fix and accumulate solar energy through photosynthesis. We systematically investigated the LCV of 745 plant species in 9 forests,Expand

Significant Phylogenetic Signal and Climate-Related Trends in Leaf Caloric Value from Tropical to Cold-Temperate Forests
Leaf caloric value (LCV) is a useful index to represent the conversion efficiency of leaves for solar energy. We investigated the spatial pattern of LCV and explored the factors (phylogeny, climate,Expand

Structural Characteristics of rocG and ure Genes of a Novel Screened Bacillus subtilis natto Strain
Natto is considered to be a health-enhancing food mainly because of nattokinase, which can lead to a mild enhancement of fibrinolytic activity in rats and dogs after oral administration. It hasExpand
Multi-objective Large-Scale Staff Allocation
Satalia is working with a multinational company that needs to have a team of 10 people spend 4 months every year manually assigning 1,000 staff to perform 10,000 jobs on 2,000 projects. This is aExpand
