As always, the usual, such as rfid inlaytechnology has a lot of supporters and opponents. In spite of all the amenities that come through the use of RFID, many people installed, sees great danger. And for good reason. In particular, the radio tag is basically a radio beacon - that in this way they are used, and even the Soviet intelligence in the 1950s. And not only unauthorized tracking, which raises concerns pose a much greater threat to the security of the technology itself. Bruce himself Šnajeris plans to install RFID tags in passports, stated, "This is a definite danger to the national security."
The introduction of electronic passports have spoken a lot. The media constantly flickering evidence that e-passport - versatile and perfect personal identification tool. But only in theory. In practice, it appears a bunch of problems. Mainstream society claims a new model for passports - RFID CARD remote scanning and recorded in the memory chip lack of encryption of personal information. It is therefore essential personality of the document confirming the content becomes available to anyone who is interested in this information.
Constantly tobul?jantiems 'personalities thieves' new electronic documents are presented, in fact, infinite "nesuartus fallow. And besides, people tend to ask personal documents only in cases where they deem it necessary, and not to any combo cards sutiktajam. In short, the state, claiming taking care of the security of citizens, in this case, only creates new problems and threats, each of which will have to defend themselves on their own.
Losing weight nowadays is certainly not always easy to participate. Meals limitations, extreme physical exercise and surgical treatments would be the widespread choices that a lot of individuals do take up.
Typically, NFC CARDdo not have their own power supply and uses a scanner device radiant energy. However, when this happens, the counting operation of each RFID scheme makes an electromagnetic field around the chip to change. Thanks to this change, a simple directional antenna can be used to track and record the energy dynamics of the chip, ie, by the signals emitted in making correct and incorrect password bits differences.
Analysts who have the right skills, easy to pick on an oscillograph peaks corresponding to incorrect bits, ie each time a new procedure with little modification neteisingojo bit, they managed to figure out quite quickly password initiating chip "suicide." After analyzing the measures required for such an operation, the researchers concluded that, in principle, sufficient for a mobile phone that can be deducted automatically self-destruct password and delete all trapped in the radiation zone of the combo cards.
It is already known that the contactless cards scanner detected when they fall into the area of operation. The reader communicates with tags, transitioning from channel to channel in a particular frequency band (902-928 GHz). It was believed to be reliable as at the interference, the scanner can switch to a different frequency. Hackers (hackers) trials were completed in the frequency range used by the mark, and this could no longer connect to the scanner. Thus, the determination of the frequency hopping mode of use does not save bookmarks from DoS attacks, because the labels fail to self-determination of frequencies.
