Tikanga Tuhimunatanga o te tiaki ngā mōhiohio: ariā, ngā āhuatanga, ngā tūranga matua

Papakupu homai tata tatou ki tahi i te tahi whakamāramatanga pū o te wā "tuhiwhakamuna", rere anake i roto i te wāhanga o tona tono. Tuhimunatanga - te pūtaiao o te pehea, ki te te tiaki i ngā mōhiohio i roto i te whānuitanga o ngā tikanga, ki te tika, whāititanga i runga i te mana ki te tirotiro i te reira me tona whakamahinga.

tikanga Tuhimunatanga o te tiaki ngā mōhiohio - ko te huringa o te mōhiohio mō tona tuku atu ki te tangata mana. Ko te parau tumu o enei tikanga ko e whai ake. Paraimere karere whakamuna tuwhera, whiwhi i te puka o te kuputuhi kati whakairoiro i huaina cryptogram ranei. tuku cryptogram anō te i runga i te hongere haumaru pāhekeheke ranei whakawhitihia ngā mōhiohio ki te fariiraa i wāhi. te maua e He kaiwhakamahi mana kōaro wetemuna ranei o te karere riro a e tango te kuputuhitōkau taketake. Ko te kupu, e kore e tangata ke te mōhio Shirograms e taea ki te pānui i te reira, kahore hoki e mohio he aha te ahua o cryptographic tikanga tiaki mōhiohio e whakamahia ana mō te whakamunatanga.

Kei te maha whakamahia te ariā o te tuhiwhakamuna matua, e taea ana ki te utu i te whakarara i waenganui i te ngā mōhiohio whakamunatia, me te pūnaha Tapa. tiaki cryptographic o ngā mōhiohio e whakamahia ana mō te whakamuna me te wetemunatanga he raupapa ahurei o pūāhua, i huaina nei ko te kī. Ko te kupu, mā te whakamahi i te hua Hātepe whakamunatanga cryptographic taua tei runga i te kī.

Kei te wehea Kī mo ratou whakarōpū ki:

• hangarite, arā te kaituku me te kaiwhiwhi i roto i te tukanga o te whakamunatanga, me te wetemunatanga te whakamahi i te taua matua, e whakarite te tapu nui o te karere whakamuna, engari hanga raruraru i roto i te mahi o te mau taviri i roto i ngā pūnaha rerekē, i reira he maha nui o ngā kaiwhakamahi;
• hangarite, i roto i te meka e whakaaro reira he rua matua, e whakarato ana i te kati (tūmataiti) me tūmatanui mau taviri.

Ko te parau tumu o te rua matua ko: whakamahia kī tūmataiti te ki te whakaputa i te kī tūmatanui, engari e kore e taea te hanga hoki ki te kī tūmatanui mohiotia. Ka āta whakarite tēnei e tirohia i te motuhēhēnga ina whakawhiti mōhiohio, hainatia e te waitohu mamati hiko (EDS).

Cryptographic tiaki pārongo mā te whakamahi i te mau taviri hangarite whai hua mō te whakamuna tuku hei utu o te mōhiohio penapena. He pai ki te whakakapi i te waitohu mua i runga i te hiko (mamati), Kei te whānui i whakamahia i roto i ngā pūnaha utu Ipurangi nga taviri tūmatanui.

tikanga Tuhimunatanga o te tiaki ngā mōhiohio e whakatau i te whakaritenga e whai ake nei:

1. He KarereHuna pūmau taea o pato cryptanalysis me te whakarato i te ara o tona whakatuwheratanga anake e mau taviri rapu ngaio. Na reira, tei te kī faaotiraa tūponotanga i runga i tona roa.
2. Ki te whakarite mauroa o te pūnaha cryptographic e humarie rokiroki kore e mau taviri ngaro me hātepe te whakamahi i ratou.
3. Hei whakaputa i te rōrahi o te mōhiohio ā e kore e e nui te taketake.
4. Whakakore distortion me te mate o te mōhiohio e tika ana ki ngā hapa ka whakamuna.
5. Ki te whakarite wā whakawaehere iti.
6. A ani i ōritetanga i waenganui i te uara whakamunatanga me te uara o te mōhiohio tuatahi.

Kei te āhuatanga e ātete o te kahore, i te mea te mehua matua o te whai huatanga tikanga Tuhimunatanga o te tiaki mōhiohio. Tenei tōtika Ko te utu i roto i te wa ranei te uara o moni e hiahiatia ana mō te whiwhi i te karere taketake decryptor i te ngaro o te kī whakawaeheretia. Engari i reira he kore paruparu i roto i hātepe whakamunatanga, e hohoro Tātaitia te kamura, me te pono te roa matua nui, tupu tino enei utu.
