Bonsai Trees (or, Arboriculture in Lattice-Based Cryptography)
We introduce bonsai trees, a lattice-based cryptographic primitive that we apply to resolve some important open problems in the area. Applications of bonsai trees include: • An efficient, stateless ‘hash-and-sign’ signature scheme in the standard model (i.e., no random oracles), and • The first hierarchical identity-based encryption (HIBE) scheme (also in the standard model) that does not rely ...

متن کاملFine Root Growth Response to Soil-Applied Nitrogen and Paclobutrazol
Practices to promote tree root growth have been sought in arboriculture for many years, especially as a treatment for trees that are stressed or in decline. Tree fertilization is a common practice in arboriculture. A few research reports have shown that nitrogen fertilization can increase fine-root density in localized areas of soil where the fertilizer has been applied, but the effect on the w...
متن کاملReturning to East Timor: Prospects and Possibilities from an Archaeobotanical Project in the New Country
In East Timor’s diversified subsistence economy, rice and maize are today common staples in some areas but root crops and arboriculture, too, play an important role. Although a cultural and chronometric framework for the introduction of agriculture in East Timor has long been proposed, little is known about the exact history of early plant use in the island. This paper deals with preliminary fi...
متن کاملEnhanced antibiotic multi-resistance in nasal and faecal bacteria after agricultural use of streptomycin
Streptomycin is used in arboriculture to control fire blight. Using sheep as a model, multidrug-resistant bacteria in mammals were found to be selected after the intentional release of streptomycin into the environment. Escherichia coli and Staphylococcus spp. were isolated from the faeces and nasal cavities, respectively, of sheep grazing on a field sprayed with streptomycin at concentrations ...
