We present a collision attack on the hash function HAS-160 reduced to 53-steps. The attack has a complexity of about 2 hash computations. The attack is based on the work of Cho et al. presented at ICISC 2006. In this article, we improve their attack complexity by a factor of about 2 using a slightly different strategy for message modification in the first 20 steps of the hash function.
Introduction: Few studies have investigated the association between dietary patterns, general and central obesity in type 2 diabetic patients. The aim of this study is to determine this relation among type 2 diabetic patients living in Tehran. Methods: In this cross-sectional study, 728 patients with type 2 diabetes from the Tehran diabetes centers were participated. Usual dietary intake ...
Class C physiologic incident reports during undergraduate pilot training (UPT) revealed that 1.7 episodes of G-induced loss of consciousness (LOC) occurred monthly in 1980-1984. The mean +Gz for the LOC episodes was +3.8 Gz; the minimum, +2.0 Gz. The mean time of total incapacitation was 12.0 s (maximum, 180.0 s) as subjectively estimated by the aircrew. Improper performance of the anti-G strai...
Searching for educational resources on the web would be greatly facilitated by the availability of classificatory metadata, but most web educational resources put up by faculty members provide no such metadata. We explore using text classification and information extraction techniques to automatically gather such metadata. Text classifications orthogonal to topic matter appear possible with hig...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
Nowadays stock market as a means to facilitate and direct micro investment for economic development is deemed as one of the most effective tools in the market economy system. Analyzing the risk and output of various companies' shares is among the most important preconditions of stock investment. In general, although conventional risk measures such as Beta and standard deviation are relatively e...
Background: High levels of heavy metals in food are general concerns including carcinogenic effects. According to studies, the accumulation of heavy metals in crops and consumption of these products in diet, has led to serious health concerns. This study investigated the concentrations of lead and cadmium in popular agricultural products. Methods: In this descriptive study, some fresh agricult...
