Faked states attack and quantum cryptography protocols
Leveraging quantum mechanics, cryptographers have devised provably secure key sharing protocols[4], [3], [6], [17]. Despite proving the security in theory, real-world application falls short of the ideal. Last year, cryptanalysts completed an experiment demonstrating a successful eavesdropping attack on commercial quantum key distribution (QKD) systems[12]. This attack exploits a weakness in th...
متن کاملFaked states attack on quantum cryptosystems
A new type of attack on quantum cryptography systems is proposed. In this attack, Eve utilizes various optical imperfections in Bob’s scheme and constructs light pulses so that Bob does not distinguish his detection results from normal, whereas they give Bob the basis and bit value chosen at Eve’s discretion. Applying this attack to systems with passive basis choice on Bob’s side is considered....
متن کاملNutritional supplements cross-contaminated and faked with doping substances.
Since 1999 several groups have analyzed nutritional supplements with mass spectrometric methods (GC/MS, LC/MS/MS) for contaminations and adulterations with doping substances. These investigations showed that nutritional supplements contained prohibited stimulants as ephedrines, caffeine, methylenedioxymetamphetamie and sibutramine, which were not declared on the labels.

متن کاملPre-Modern and Early Modern Persian Literature: Written while Travelling?
In literary histories written in both Iran and the West it has generally be assumed that early modern Persian literary works are (technically inferior) copies of Western literary works. This has been and is still a claim. Almost no academically and scientifically sound works has substantiated this claim. While there is no point in denying a European influence on early modern Persian literature,...
متن کاملArchaeological Excavations and Finding Antiques by European Travelers and Orientalists during Qajar Era
The history of new and scientific archaeological researches in Iran mainly dates back to the Qajar period. Although the history of European Oriental studies in Iran has exceeded the Qajar era, however, until the aforementioned period, scientific archeology in Iran did not have much meaning and European officials and Orientalists studies in Iran mainly focused on the identification of Iranian an...
