Toxic Christmas and New Year Holiday Plants...or Are They?
Background: Poinsettia (Euphorbia pulcherrima), holly (Ilex opaca) and mistletoe (Phoradendron flavescens) adorn homes during the Christmas and New Year holiday season and create the potential for curious children to sample their colorful leaves and enticing berries. This study was aimed to review the American Association of Poison Control Centers National Poison Data System (AAPCC NPDS) to des...
متن کاملPolly Cracker, Revisited
In this work, we initiate the formal treatment of cryptographic constructions (“Polly Cracker”) based on the hardness of computing remainders modulo an ideal. We start by formalising and studying the relation between the ideal remainder problem and the problem of computing a Gröbner basis. We show both positive and negative results. On the negative side, we define a symmetric Polly Cracker encr...
متن کاملLattice Polly Cracker cryptosystems
Using Gröbner bases for the construction of public key cryptosystems has been often attempted, but has always failed. We review the reason for these failures, and show that only ideals generated by binomials may give a successful cryptosystem. As a consequence, we concentrate on binomial ideals that correspond to Euclidean lattices. We show how to build a cryptosystem based on lattice ideals an...

متن کامل‘ ‘ Foiling the Cracker ’ ’ : yA
c Unix. When Unix was younger, the password encryption algorithm was a simulation of the M-209 ipher machine used by the U.S. Army during World War II [Morris1979]. This was a fair encryption s t mechanism in that it was difficult to invert under the proper circumstances, but suffered in that it wa oo fast an algorithm. On a PDP-11/70, each encryption took approximately 1.25ms, so that it was p...
