We develop a number of techniques for the cryptanalysis of the SHA-3 candidate Luffa, and apply them to various Luffa components. These techniques include a new variant of the rebound approach taking into account the specifics of Luffa. The main improvements include the construction of good truncated differential paths, the search for differences using multiple inbound phases and a fast final s...
The strain rate effect of luffa sponge material is an indispensable property for it to be used for acoustic, vibration, and impact energy absorption. Compressive tests at different strain rates on cylindrical column specimens of luffa sponge material were conducted over a wide density ranging from 24 to 64 kg/m. A photographic technique was applied to measure the section area of the specimen wi...
