Vatsvakurudzi kubva kuDavid Ben-Gurion University (Israel), kudzidza nzira dzakavanzika dzekufambisa data kubva kumakomputa ari ega, nzira itsva yekuronga nzira yekukurukurirana yakavakirwa pakuchinja kwechiratidzo kuburikidza nekushanduka kusingaoneki mukupenya kweLCD skrini. Padivi rinoshanda, iyo nzira inogona kushandiswa, semuenzaniso, kuendesa encryption kiyi, mapassword uye zvakavanzika data kubva komputa isina network yekubatanidza uye inotapukirwa nespyware kana malware.
Kuisa encode "1", kuwedzera kwekupenya kwechikamu chitsvuku chepikisi ruvara ne 3% maererano nehuwandu hwezita hunoshandiswa, uye "0" kuderera kwekupenya ne3%. Shanduko mukupenya kunoitika panguva yekuchinjisa data haionekwe nevanhu uye nzira yacho inogona kushandiswa kunyangwe mushandisi ari kushanda pakombuta iyo data iri kutorwa. Ruzivo rwakagadziridzwa kuburikidza nekuchinja mukupenya runogona kutorwa kubva mumavhidhiyo zvakarekodhwa, kusanganisira ayo akatorwa neCCTV kamera, webhu kamera uye mafoni.
Mutengo wekutamisa mabhiti mashoma pasekondi. Semuenzaniso, pakushandisa Sony SNC-DH120 720P vhidhiyo yekutarisa kamera uye Microsoft Lifecam web kamera, takakwanisa kugamuchira data kubva kure kusvika ku9 metres nekumhanya kwe5-10 bits pasekondi. Paunenge uchishandisa kamera yeSamsung Galaxy S7 smartphone, chinhambwe chekugamuchira chiratidzo chakaderedzwa kusvika mita imwe nehafu, uye kumhanya kwekutapurirana kwakadonha kusvika 1 bit pasekondi.
pamusoro kusarudzwa kwedzimwe nzira dzekuvharidzira data kufambisa dzakadzidzwa nevaongorori vachishandisa electromagnetic, acoustic, thermal uye mwenje mafomu ekuvuza akaumbwa zvakare:
- - kutumira data pamusoro petambo yemagetsi, kugadzirisa mutoro paCPU kushandura kushandiswa kwesimba;
- () - dhata kunze kweinonzwika renji kuburikidza nevanongotaura kana mahedhifoni pasina kushandisa maikorofoni;
- () - kuratidzwa kwekutorwa kwedata kubva pachigadzirwa chiri muimba yakadzivirirwa (Faraday cage) kuburikidza nekuongorora kwepasi-frequency magnetic oscillations inoitika panguva yekushanda kweCPU;
- () - kudhirowa kwedata kwakavakirwa pakuyera magineti kushanduka kunoitika panguva yeCPU kushanda;
- () - kufambisa data nekumhanya kweanosvika 60 bytes pasekondi kubva kuPC kuenda kune smartphone kuburikidza nekuongorora pane smartphone ine FM tuner yekukanganisa redhiyo inoitika kana ichiratidza ruzivo pachiratidziro;
- () - kuendesa data pamusoro pechinhambwe chinosvika 40 cm nekumhanya kwe1-8 bits paawa kuburikidza nekuyera kushanduka kwekushisa kwePC kesi;
- () - kuburitsa data kureba inosvika makumi matatu metres kuburikidza nekugadzirwa kwemagetsi kupindira kweiyo frequency yeGSM network inotorwa ne smartphone;
- () - kuendesa data nekumhanya kwe180 bits paminiti kuburikidza nekuongororwa kwemanzwi akaitwa pakubata hard drive;
- () - kuendesa data nekumhanya kweanosvika makumi masere mabheti pasekondi kuburikidza nekuongororwa kwemagetsi kukanganiswa kwemagetsi kwakagadzirwa panguva yekuwana zvishandiso kuburikidza ne USB port;
- () - kushandiswa kwe LED kunoratidza basa reiyo hard drive senzvimbo yekufambisa data nekumhanya kusvika ku120 bits pasekondi kana uchishandisa yakajairika vhidhiyo kamera seanogamuchira uye anosvika 4000 mabhiti pasekondi kana uchishandisa yakakosha sensor;
- () - Kuchinjisa data nekumhanya kweanosvika mazana mapfumbamwe mabhiti paawa kuburikidza nemodulation yekuchinja kwekurira kweinotonhorera inoshandiswa kutonhodza CPU;
- () - kuendesa data kuburikidza neiyo infrared LED yemakamera ekutarisa nekumhanya kwe100 bits pasekondi uye kureba inosvika kiromita;
- () - kuendesa data nekumhanya kunosvika zviuru gumi zvebhiti pasekondi kuburikidza nekubwaira maLED pane hacked routers uye switch;
- -kufambiswa kwedata kuburikidza nekupenya kusingaonekwe kana shanduko mukusiyana kwemufananidzo uri pachiratidziri.
