Iyo ichangobva kuburitswa kunetseka mu iyo isina waya standard Bluetooth inogona kubvumira vabiridzi kuti vabatanidze kumidziyo uri kure mune imwe nharaunda uye shandisa zvinoshandiswa zvevashandisi.
Iyo kushupika, inonzi Blurtooth, yakatsanangurwa mazuva mashoma apfuura neiyo indasitiri muviri Bluetooth SIG uyo anoona nezvekuvandudzwa kwechiyero. Uye ndeyekuti bluetooth inowanikwa mumabhirioni emidziyo kutenderera pasirese, kubva kumafoni efoni kusvika kumidziyo yeIoT "Internet yezvinhu".
Kunetseka kwaBlurtooth Yakawanikwa nevatsvagiri ve EPFL École Polytechnique Fédérale de Lausanne uye iyo Purdue University yeSwitzerland.
Munyika yehunyanzvi hwevatengi, inowanzo shandiswa kumisikidza mapfupi-renji ekubatanidza ezvemabasa senge yekubatanidza isina waya mahedhifoni nefoni.
Asi Bluetooth zvakare inotsigira kureba-renji dhata yekuchinjisa pamadhizaini anosvika mazana emamirimita emamita, renji ingabiwa nevaseki vachishandisa Blurtooth kutanga kurwisa.
Iyo kusagadzikana kunoshandisa kushaya simba munzira iyo Bluetooth inosimbisa iko kuchengetedzwa kwekubatana.
Kazhinji, mushandisi anofanira kubvumidza nemaoko chikumbiro chekubatanidza mudziyo wavo usati wabatanidzwa kune imwe sisitimu, asi Blurtooth inobvumira kudzivirira uku kutenderedzwa.
Sezvo mushambadzi kana mumwe munhu ane ruzivo rwakakwana kushandisa kusagadzikana inogona kumisikidza yakaipa system yekuedzesera kifaa cheBluetooth kuti mushandisi anga atove yakatenderwasenge mahedhifoni asina waya uye kuwana kweBluetooth-inogoneswa kunyorera pamushini wemushandisi.
Kurwiswa kwaBlurtooth kwakavakirwa pa yakavakirwa-muBluetooth chengetedzo ficha inozivikanwa se CTKD. Kazhinji, iri basa inoshandiswa kubatsira kunyorera kubatanidza. Asi mubiridzi anogona kuishandisa kuti akwanise kuwana kiyi yekusimbisa yechinhu chakatenderwa kare, zvinova zvinoita kuti zvikwanise kuburitsa magumo epamutemo nekudaro kudzikisira kudiwa kwemushandisi kubvumidza kubatana kuri kuuya.
Iyo yakaganhurirwa isina waya renji yeBluetooth inoderedza kutyisidzira kunokonzerwa nekushupika. Iwo maviri edhisheni yeiyo yakakanganiswa tekinoroji, Low Energy uye Basic Rate, chete rutsigiro kubatana pane madaro anosvika angangoita mazana matatu tsoka. Asi kutsigirwa kwakapararira kweaya maviri maBluetooth edhisheni pamidziyo yevatengi zvinoreva kuti huwandu hwakawanda hwetemu hunogona kuve hunogona kutambura.
Iyo indasitiri muviri we Bluetooth SIG yakataura izvozvo mamwe emidziyo anoshandisa zvinyorwa Bluetooth 4.0 kusvika 5.0 inobatika. Iyo yazvino vhezheni 5.2, iyo isati yambotambirwa zvakawandisa, zvinoita kunge isiri panjodzi, nepo vhezheni 5.1 iine zvimwe zvakavakirwa-mukati izvo zvinogadzira zvigadzirwa zvinogona kugonesa kurwisa Blurtooth.
Pakukurumidza kukurudzira, Bluetooth SIG Yakati iri "kutaurirana zvakanyanya" ruzivo rwekushomeka nevakagadzira michina kuti ikurumidze kupindura kwemaindasitiri. Boka "rinovakurudzira kuti vakurumidze kubatanidza zvidimbu zvinodiwa." Izvo hazvisati zvajeka kana izvo zvigamba zvichave zviripo kana kuti ndeapi michina anozozvida iwo.
Iyo Bluetooth SIG yakaburitsa chirevo chinotevera neChishanu:
Tinoda kupa kumwe kujekesa pane iyo BLURtooth kudzvinyirirwa. Chirevo chekutanga cheveruzhinji cheBluetooth SIG chakaratidza kuti kushomeka kunogona kukanganisa zvishandiso zvinoshandisa vhezheni 4.0 kusvika ku5.0 yezvakakosha zveBluetooth.
Nekudaro, izvo izvo zvakagadziriswa kuratidza chete vhezheni 4.2 uye 5.0. Zvakare, iyo BLURtooth kudzvinyirirwa hakukanganisa zvese zvishandiso zvinoshandisa idzi shanduro.
Kuti ive inokwanisa kuvhurika kurwisa, chishandiso chinofanirwa kutsigira zvese BR / EDR uye LE panguva imwe chete, tsigira kuyambuka kiyi yekutakura kiyi, uye wedzera kutarisa nekutora makiyi mune imwe nzira. Mhinduro yedambudziko iri inotsanangurwa muBluetooth Basic Specification 5.1 uye gare gare, uye iyo Bluetooth SIG yakurudzira nhengo dzine zvigadzirwa zvinotambura kuisa shanduko iyi mukugadzira kwekare, pazvinogoneka.
Chekupedzisira zvinotaurwa kuti vashandisi vanogona kuteedzera kuti kana yavo kifaa yagamuchira chigamba cheBURURtooth kurwiswa nekutarisa iyo firmware uye inoshanda sisitimu yekuburitsa manotsi e CVE-2020-15802.
