Cornell University Researchers Demonstrated GPS Vulnerability with Spoofing Activities Cornell University raziskovalci dokazali GPS ranljivost s Zgrešek dejavnosti
Nowadays GPS (Global Positioning System) usage is so common with almost all high end cellular phones are embedded with GPS receiver module. Danes GPS (Global Positioning System) je zato skupna uporaba s skoraj vsemi visoko koncu mobilnih telefonov so vgrajeni z GPS modul. While it brings convenience to daily life, but too much relying on it may potentially cause serious issue in certain scenario. Medtem ko prinaša priročno za vsakdanje življenje, toda preveč se zanašajo na to bi lahko povzročilo resen problem v nekaterih scenarij. Just recently, a team of researchers from Cornell University have demonstrated a way on how to fool the GPS units by sending out false signal that imitate actual satellite signal patterns. Samo pred kratkim, je skupina raziskovalcev na Univerzi Cornell so pokazala, da je način, kako norec GPS enote, ki jih poąiljanja iz napačnih signalov, ki posnemajo dejanske satelitskega signala vzorcev. Those signals will be interpreted by the GPS receivers as a genuine signal which causes the wrong position information being retrieved by end users. Tiste signale, ki jih bo treba razlagati GPS sprejemnikov kot pristni signala, ki povzroči napačne informacije, ki jih nalagajo končnim uporabnikom. For normal consumers, it may be still alright but the consequence could be very serious especially when such a scenario happens in military applications. Za običajni potrošniki, lahko še vedno v redu, ampak posledica je lahko zelo resna, zlasti kadar takšen scenarij se zgodi v vojaške aplikacije.
GPS receiver is capable to lock to at least four satellites orbiting around the earth to obtain accurate positioning information through specific pattern signals. GPS je zmožna zaklepa na vsaj štirih satelitov v orbiti okoli Zemlje, da pridobijo točne informacije, s pomočjo posebnega položaja vzorec signalov. But somehow these signals can be duplicated by this programmable transmitter, putting the whole system reliability questionable. Ampak nekako ti signali lahko podvaja s tem lahko programira oddajnik, da je zanesljivost celotnega sistema vprašljiva. Although existing transmitter is quite large in size, about the size of a suitcase, but it is foresee that the size can be shrunk down as small as a cigarette pack, making the proximity attack possible anywhere without the users’ acknowledgment. Čeprav se obstoječi oddajnik je precej velik, v velikosti, o velikosti kovček, vendar se predvideva, da se lahko velikost shrunk, kot majhen kot paket cigaret, ki na bližino napad mogoče kjerkoli brez uporabnikov povratnico. Just imagine how dangerous would it be if this tiny device can jeopardize the whole rescue effort when a rescue team has been dispatched but unable to identify the right location due to wrong GPS data. Zamislite si, kako nevarno bi bilo, če te lahko ogrozili drobnih naprava celotnega napora za reševanje, ko je reševalna ekipa bila odposlana, vendar ne morejo določiti prave lokacije zaradi napačne Podatki GPS.
Hopefully the demonstration and study results will trigger the way how GPS designers defining their next generation GPS products with a more thorough and full proof GPS release to the market in short future. Upajmo, da se dopolnjujejo predstavitvene dejavnosti ter rezultate študije bodo prikazale način, kako GPS oblikovalci opredeljevanju njihovih naslednjo generacijo GPS proizvodov z bolj natančnim in popolnim dokazilo GPS sprostitvi na trg v kratkem prihodnosti.
