This paper presents a new attack on keyboards. The attack consists in depositing on each keyboard key a small ionic salt quantity (e.g. some NaCl on key 0, some KCl on key 1, LiCl on key 2, SrCl2 on key 3, BaCl2 on key 4, CaCl2 on key 5...). As the user enters his PIN, salts get mixed and leave the keyboard in a state that leaks secret information. Nicely enough, evaluating the entropy loss due...

The Japanese Sect Aum Shrinryko launched their terrorist attack on the Tokyo Underground on the 20 March 1995. Five terrorists boarded underground trains heading for the Kasumigaseki station carrying at least two bags each of liquid Sarin (Isopropyl methylphophonofluoridate ) wrapped in newspaper. These were punctured with the sharpened tip of an umbrella prior to the escape of the perpetrators...

radio frequency identification (rfid) applications have spread all over the world. in order to provide their security and privacy, researchers proposed different kinds of protocols. in this paper, we analyze the privacy of a new protocol, proposed by yu-jehn in 2015 which is based on electronic product code class1 generation 2 (epc c1 g2) standard. by applying the ouafi_phan privacy model, we s...

The yellow-legged hornet, Vespa velutina nigrithorax, is an invasive species that causing numerous ecological and economic problems, particularly for beekeepers, whose apiaries are seriously affected by hornet predation. effects may be intensified if workers from different colonies preying upon bees the same apiary. Therefore, to determine whether such could occur, we sampled hornets found with...

Although chemical predator cues often lead to changes in the anti-predator behavior of animal prey, it is not clear whether non-volatile herbivore kairomones (i.e. incidental chemical cues produced by herbivore movement or metabolism but not produced by an attack) trigger the induction of defense in plants prior to attack. I found that unwounded plants (Brassica nigra) that were regularly expos...
