In this paper, we present the pseudo-collision, pseudo-second-preimage and pseudo-preimage attacks on the SHA-3 candidate algorithm Luffa. The pseudocollisions and pseudo-second-preimages can be found easily by computing the inverse of the message injection function at the beginning of Luffa. We explain in details the pseudo-preimage attacks. For Luffa-224/256, given the hash value, only 2 iter...

In the present paper the systematic enumeration of Cucurbit germplasm of Bihar State has been described. The three genera recorded from field were Luffa, Momordica and Trichosanthes. Three species of Luffa, five species of Momordica and three species of Trichosanthes were collected and described in detail.

Indifferentiability is currently considered to be an important security notion for a cryptographic hash function to instantiate Random Oracles in different security proofs. In this paper, we prove indifferentiability of Fugue and Luffa, two SHA3 second round candidates. We also analyze the indifferentiability of a modified Luffa mode replacing multiple small permutations by a single large permu...

Nature has been a source of medicinal agents for thousands of years, herbal medicines which formed the basis of health care throughout the world since the earliest days of mankind are still widely used. Luffa acutangula is widely growing vegetative climber and is used traditionally in folklore medicines for ailments including jaundice, diabetes, liver diseases, skin diseases, wounds etc. Taking...

Luffa is a new hash algorithm that has been accepted for round two of the NIST hash function competition SHA-3. Computational efficiency is the second most important evaluation criteria used to compare candidate algorithms. In this paper, we describe a fast software implementation of the Luffa hash algorithm for the Intel Core 2 Duo platform. We explore the use of the perfect shuffle operation ...

Propionic acid production from glycerol was studied using Propionibacterium acidipropionici DSM 4900 cells immobilized on polyethylenimine-treated Poraver (PEI-Poraver) and Luffa (PEI-Luffa), respectively. Using PEI-Luffa, the average productivity, yield and concentration of propionic acid from 40 g L(-1) glycerol were 0.29 g L(-1) h(-1), 0.74 mol(PA) mol(Gly)(-1) and 20 g L(-1), respectively, ...

Phylogenetic Analysis of Some Indigenous and Non-Indigenous Luffa (Luffa cylindrica) Genotypes using ITS Marker

The present study aimed to assess the hypoglycemic and antihyperglycemic activity of fruit methanolic extract of Luffa cylindrica fruits. The effect of methanolic fruit extract on oral glucose tolerance and its effect on normoglycemic rats were studied. The same was tested for antihyperglycemic activity in alloxan induced hyperglycemic rats at the two dose levels 200 and 400 mg/kg body weight p...

In vitro studies were carried out to evaluate the cytotoxic potential of the ethanolic and aqueous extracts of Luffa acutangula against human neuronal glioblastoma cells (U343) and human lung cancer cells (A549). Screening of these extracts was done using the brine shrimp lethality bioassay, MTT assay and SRB assay. The results showed the significant decrease of the viability of the cells in a ...

Bio-ethanol production from cane molasses (diluted to 15 % sugar w/v) was studied using the bacterium, Zymomonas mobilis MTCC 92 entrapped in luffa (Luffa cylindrica L.) sponge discs and Ca-alginate gel beads as the immobilizing matrices. At the end of 96 h fermentation, the final ethanol concentrations were 58.7 ± 0.09 and 59.1 ± 0.08 g/l molasses with luffa and Ca-alginate entrapped Z. mobili...
