Security of Sponge structures
Sponge structure is a structure widely used in the design of cryptographic algorithms that reduces the design of the algorithms to the design of a permutation or pseudo-random function. The development of sponge-based algorithms and the selection of designs based on this structure in SHA3 and CAESAR competitions increase the need to examine its security against various types of attacks. In the ...
متن کاملSponge Functions
A good cryptographic hash function should behave like a random oracle: it should not have weaknesses that a random oracle does not have. Due to the existence of inner collisions, iterated hash functions can never satisfy this ideal. We propose a construction with a finite state called a sponge and show that a random sponge can only be distinguished from a random oracle due to inner collisions. ...
متن کاملSponge white patch disease affecting the Caribbean sponge Amphimedon compressa.
We report on a novel sponge disease, hereafter termed 'sponge white patch' (SWP), affecting the Caribbean sponge species Amphimedon compressa. SWP is characterized by distinctive white patches of variable size that are found irregularly on the branches of diseased sponges. Nearly 20% of the population of A. compressa at Dry Rocks Reef, Florida, USA, showed symptoms of SWP at the time of investi...
متن کاملSponge cytogenetics - mitotic chromosomes of ten species of freshwater sponge.
Porifera (sponges) are the most basal phylum of extant metazoans. To gain insight into sponge genome construction, cytogenetic analysis was performed for ten freshwater sponge species of six genera, using conventional Giemsa staining, chromosome banding, and fluorescence in-situ hybridization. The karyotypes were very similar among the ten species, exhibiting a diploid chromosome number of 2n=4...
