EDS - waa maxay? Saxiixa Digital: edbinta ah bilowga ah

Saxiixa Electronic - jaantuska xisaabeed si ay u muujiyaan xaqiiqada fariimaha elektarooniga ah ama waraaqaha. A saxiixa digital ansax siinayaa sabab kasta in ay aaminsan yihiin qaataha in fariinta waxaa la abuuray by diraha la yaqaan, runtii diray (sugida iyo isku halaynta), iyo sidoo kale xaqiiqada ah in warqadda aan la bedelay intii lagu jiray gudbinta (daacadnimada).

Jawaabay su'aasha ah: "EDS - waxa ay tahay" - waxaa xusid mudan in saxiixyada digital jira feature a caadiga ah ee ugu badan hab-qaybood cryptographic oo caadi ahaan loo isticmaalo si loo qaybiyo software, macaamil maaliyeed, iyo sidoo kale xaaladaha kale oo badan marka waxaa muhiim ah si loo ogaado been- ama been.

saxiixyada Digital waxaa inta badan loo isticmaalaa in lagu fuliyo saxiixyada electronic. Kani waa erey ballaaran oo waxaa loola jeedaa nooc kasta oo xog electronic. Si kastaba ha ahaatee, ma saxiixa kasta oo elektaroonik ah waa digital.

saxiixyada Digital isticmaali cryptography sinnayn. Marar badan, ay bixiyaan heer qaar ka mid ah xaqiijinta amniga iyo farriimaha in loo diray in ka badan channel aan xasiloonayn. Marka si fiican loo fuliyo, saxiixa digital soo jeedisay in fariinta loo diray isticmaalaya diraha sheegtay. daabacaadda Digital iyo saxiixyada u dhigmaa saxiixyada lagu qoray iyo daabacaadda dhabta ah.

EDS - waa maxay?

saxiixyada Digital la mid ah saxiixyada qoray dhaqanka siyaabo badan yihiin, inta ay yihiin oo dheeraad ah ay adag tahay in Abuuran badan lagu qoray. qorsheyaasha saxiixa Digital yihiin qaabka cryptographic iyo waa in la sameeyaa si sax ah si looga fogaado in laga badiyay hufnaan. Sidee in ay saxeexaan in la saxiixa digital? Waxaad u baahan tahay in aad isticmaasho 2 lammaane oo fure u crypto.

EDS sidoo kale hirgelin karaan mabda'a non-jidha. Taas macnaheedu waa in macmiilka ah ma ku doodi karin in uusan saxiixi fariinta. Intaa waxaa dheer, qaar ka mid ah dhismeyaasha bixiyaan stamp waqtiga saxiixa ah digital ah, iyo xataa haddii ay fure u gaar ah la kulmin, saxiixa waa ansax ah. Saxiixa Electronic matali karaa sida xadhigga yara, oo lagu saleyn karaa e-mail, heshiisyada ama fariin u soo diray via maamuuska kasta cryptographic.

cryptography Public-fure ama qaab-dhismeedka saxiixa digital

Waa maxay? The nidaamka saxiixa digital ka mid ah saddex algorithms isku mar.

geynta dhalin muhiim ah in doorteen fure sir ah oo isku at random ka hannaanka ka mid ah ay suuragal tahay qayb ahaan. Waxa uu ku siinayaa fure sir ah oo isaga la socday in labada ciyaaryahan furan.

Saxiixa geynta in, siin fariin iyo fure gaar ah in si dhab ah abuuraa saxiixa.

Saxiixa geynta xaqiijinta, taas oo la tixgelinayo fariinta, furaha dadweynaha iyo saxiixa oo aqbala ama beeniyey fariin u dirayay, go'aaminta siidaayay.

Sidee si loo soo dajiyo elektarooniga saxiixa?

Si aad u isticmaasho saxiixa ah digital, waa in aad ku siin doonaan laba guryaha aasaasiga ah. Waxa aad u baahan tahay in laga fekero inta aan saxeexaya dukumentigan la saxiixa digital?

Waa midda koowaade, siidaayay of saxiixa ahbaa ka farriin go'an oo muhiim ah oo qarsoodi ah la xaqiijin waxaa laga yaabaa in la isticmaalayo macluumaadka dadweynaha u dhigma.

Marka labaad, waa in ay noqon computationally infeasible inay doortaan saxiixa sax ah oo aan og fure sir ah. EDS waa hab ah sugida oo kuu ogolaanaya in posts abuuraha lifaaq code in u dhaqmo sida saxiixa ah.

Isticmaalka saxiixyada digital

Sida maanta ururada u guurayso ka fog ee ku saleysan warqadaha dokumentiyada la saxiixooda, lagu sameeyo khad saxiixa qasac ku siin dheeraad ah hubaasha xaqiiq tahay iyo caddaynta qoray, aqoonsiga iyo xaaladda oo ka mid ah dokumentiga. Intaa waxaa dheer, saxiixa digital laga yaabaa in loola rumayn oggolaanshaha la wargeliyey iyo ansixinta saxiixayaasha ah. Sayidka, saxiixa electronic loogu talagalay dadka - mid dhab ah.

sugida

In kasta oo xaqiiqda ah in warqadda ka mid noqon kara macluumaad faahfaahsan oo in markasta suurtagal ma aha in loogu kalsoonaan karo loo ogaado diraha. saxiixyada Digital loo isticmaali karaa in sugee isha fariimaha. Marka saxiixa qarsoodi ah oo muhiim ah ku xidhan yahay user gaar ah, tani ayaa xaqiijiyay in fariin uu soo diray iyagii. Qiimaha kalsoonida in diraha waa dhab, gaar ahaan waa cad in waaxda maaliyadda.

daacadnimadayda

In xaaladood badan, ka diraha iyo qaataha ah ee fariinta u baahan tahay inaad xaqiijin saxda ah in aan la beddeli karo inta lagu jiro gudbinta. Inkastoo encryption dhuuntaa ka kooban yahay shayga u soo diray, waxaa suurtagal ah in la beddelo oo keliya fariin Windows XP aan fahamka macnaheeda. Qaar ka mid ah algorithms encryption ay awoodaan in ay tani hortago, laakiin ma aha in kiisaska oo dhan. Si kastaba ha ahaatee, ka hubi saxiixa elektaroonik ah in warqado deciphering ogaadaa xadgudub ku ah sharafta.

Si kastaba ha ahaatee, haddii fariinta waxaa dijital ah u saxiixay, isbedel kasta oo isaga ka dib saxiixii invalidates saxiixa. Intaa waxaa dheer, ma jiraan wax hab wax ku ool ah in la beddelo fariin iyo dhalin mid cusub la saxiixa sax ah, sababtoo ah waxaa la arkaa in ay computationally infeasible.

Non-jidha

Non-jidha ama ay adagtahay in waraaqaha diidmada ka soo jeedo waa arrin muhiim u ah horumarinta saxiixa electronic. Waa maxay? Taas macnaheedu waa in cidda sharci, u soo dirto qaar ka mid ah macluumaadka aan ka diidi karin in ay u saxiixay. Sidoo kale, helitaanka furaha dadweynaha uma uu oggolaado in weerarka si Abuuran saxiixa sax ah. Waxay sidaan cawaaqib isku mid ah iyo arjiga codsiga oo ah saxiixa electronic shakhsiyaadka.

Waa in ay diiradda saaraan xaqiiqada ah in dhammaan sifooyinka siidaayay, isku halaynta, iwm Waxay ku xiran tahay fure sir ah, kaas oo waa in aanay noqon ka hor ay la isticmaalo. furayaasha bulshada waa in la bedello in labada nin la qarsoon isticmaalka ka dib. Hubinta saxiixa saabsan mowduuca "Review" aadin waayo su'aal gaar ah.

Ku qor fure sir ah oo ku saabsan kaarka smart

All cryptosystems in ku shaqeeyaan on mabda'a ah ee la isticmaalayo muhiimka ah dadweynaha / gaarka ah, si buuxda u madax banaan xogta waxyaabaha qarsoon. fure sir ah EDS lagu kaydin karaa on computer user ee, iyo in la ilaaliyaa by password a degaanka. Si kastaba ha ahaatee, habkan uu leeyahay laba cillado:

• user saxiixi karaa oo keliya waraaqaha on computer in si gaar ah;
• ammaanka muhiimka ah ee gaarka loo leeyahay waxay ku xiran tahay gebi ahaanba ku saabsan ammaanka ee aad computer.

alternative A dheeraad ah oo lagu kalsoonaan karo si loogu kaydsado fure sir ah - Kaarka smart. Kaararka badan oo smart difaac ka faragelinta aan la ogalayn.

Sida caadiga ah, user waa in ay dhaqaajiso uu kaarka smart by galaya lambarka aqoonsiga shakhsiga ah ama ku-PIN code (sidaas siinaya sugida laba-factor). Waxaa la diyaarin karaa si fure u gaar ah marnaba ka baxo kaadhka smart, inkasta oo ay tani had iyo jeer ma ogaaday in CryptoPro EDS.

Haddii kaarka smart la xado, weeraryahanka weli u baahan tahay lahaa PIN-code in la abuuro saxiixa ah digital. Tani waxay wax yar ka yaraynaysaa ammaanka ee nidaamka this. Khafiifinta factor waa in furayaasha ahbaa, haddii ay ku kaydsan yihiin kaararka smart, sida caadiga ah, ay adag tahay in nuqul, waxaa la qiyaasayo in ay ka jiraan kaliya in hal nuqul. Sidaas darteed, marka khasaaraha card smart la ogaado qofka leh, shahaado waa lagala karo. furaha gaarka loo ilaaliyo oo keliya by software, waxaa ka hawl yar in aad nuqulka, iyo darroor oo kale waa dhib badan in la ogaado. Sidaa darteed, isticmaalka saxiixa elektaroonik ah oo aan wax difaac dheeraad ah waa ammaan ahayn.
