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 کاملHuman mandible bone defect repair by the grafting of dental pulp stem/progenitor cells and collagen sponge biocomplexes.
In this study we used a biocomplex constructed from dental pulp stem/progenitor cells (DPCs) and a collagen sponge scaffold for oro-maxillo-facial (OMF) bone tissue repair in patients requiring extraction of their third molars. The experiments were carried out according to our Internal Ethical Committee Guidelines and written informed consent was obtained from the patients. The patients present...

متن کاملBone formation around rhBMP-2-coated implants in rabbit sinuses with or without absorbable collagen sponge grafting.
PURPOSE The purpose of this study was to evaluate bone formation around recombinant human bone morphogenetic protein (rhBMP-2)-coated implants placed with or without absorbable collagen sponge (ACS) in rabbit maxillary sinuses. METHODS The Schneiderian membrane was elevated and an implant was placed in 24 sinuses in 12 rabbits. The space created beneath the elevated membrane was filled with e...
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. ...
