Kamepiula 'ē aʻe, Maluhia

Algorithms no kaʻikepili encryption. Symmetric encryption algorithms. RSA encryption algorithm. Des encryption algorithm. E koho i ka encryption algorithm

I ko makou kamepiula makahiki manaʻo kanaka increasingly aole e hoahu 'ike i loko o puke a paiia palapala, hoopakela aku e hana uila palapala. A ina ma mua aihue ana i kekahi pepa a parchment, akā manawa ka mea, ua poha i loko o lolouila ike. Ia lakou iho me algorithms ʻikepili encryption ua, ua hoikeia mai ka pō mai. Ua nui maikai ana i makemake ko e encrypt kā lākou hanana ike, no laila, i ka mea hiki ke kiʻi wale nō kanaka ike. Akā, e ka ike pehea ka mea, ua hōʻike 'ia ma luna o mākou honua.

He aha mea heʻikepili encryption kahua?

E hoʻomaka i ka hooholo i ka ho i ka cryptographic nenoaiu i mau. 'ōlelo koʻikoʻi akula olelo ana, i kēia mea he kūikawā algorithm no ka kākau i 'ike, a makemake e maopopo wale i ka kekahi pōʻai o kanaka.

Ma keia ano, he malihini na mea a pau kana i ike mai, e (ma ka rula, ia mea) mea meaningless 'ia paha o nā huapalapala. E heluhelu i ka ke kaʻina, ke wale nō kekahi mea i ike i ka rula o ko lākou mau wahi. E like me ka nui loa na mea hoʻohālike, e hiki ke hoʻoholo i ka encryption algorithm me ka pela 'ana o olelo, no kekahi laʻana, hoʻi i ka mua. O ka holo ana, i kēia mea i ka loa primitive, e hiki manaʻo o. Ke implication ka mea ina oe i na rula o ke komo, e hoihoi mai i ka palapala kikokikona i ole hana.

No ke aha la hana ia?

He aha ka mea a pau e hiki mai me ka mea paha e pono e hoomaopopo. E nana mai, no ka mea nui o ka 'ike i koe e kahiko maikai ana, e ano hoʻopā'āluaʻia. Ina paha o ka poʻe kahiko i ole makemake mākou e loaʻa mai, ina paha ia i nā mea a pau hana, i ke kanaka, ua hiki ke hana ia wale nō ka wā o ka makemake nui o? Acaeoey - aole nae ia hiki wale koho.

Eia naʻe, ina ua kamailio e pili ana i keia la i ka honua, palekanaʻikepili ua lilo kekahi o ka mea nui pilikia. Hoopai aku no oe ia oe iho, no ka mea, e haule ana na palapala he nui loa i loko o ka palapala o ka mea hookahi, i kekahi aupuni e makemake mai i ka pili, pehea na koona huna i ike loea hou. Akā, i kēia mea, ma ka a me ka nui, o ka iniiaiie manao o ka ai-kapaia hackers, ma ka Classic ano o ka makahiki.

Ua hele mai e hoomanao hoʻokahi wale hopuna'ōlelo mea i lilo i ka Classic nā loina o ka ha awina Natana Rotshilda: ", Owai la ka mea nona ka ike, nona ke ao nei" A me ia mea ke kumu o ka 'ike e pono e hoʻopale mai prying mau maka, no laila, ia ia i ole hana houʻo ia no lākou iho p'mau hana.

Cryptography: ka ho omaka

Ano, ma mua noonoo i ka mea 'ole e loaʻa kekahi encryption algorithm, he uuku he tutua kai i loko o ka moʻolelo, i loko o ia mau lā, i ka wa a ka' epekema i loko o kona uuku.

Ua Ua manaoio aku i ka nō o ka hunaʻikepili hoomaka 'Imi e hoʻoikaika mau tausani makahiki mua mākou'āina. Superiority ua aie i ka Sumerians kahiko, ke alii Solomona, a me ka Aigupita kahuna. Wale nui hope, o ka mea ia runic huapalapala a me nā hōʻailona nō hoʻi e like. Akā, i mea hana hoihoi ': kekahi manawa kikokikona encryption algorithm (ʻo ia, e codified ka mea, i ka manawa) ua ia ma ka ia kahiko Sumerian cuneiform kekahi ano hiki ke manao ole wale kekahi palapala, akā, i ka mea a pau olelo, manaʻo paha hoi a'ōlelo hoʻohali. No ka mea, o keia ano o kēia mau hāʻina o nā haʻawina, a hiki i ke kālā no cryptographic nenoai hele 'ana o ka palapala helehelena o kekahi kikokikona e hoihoi, ia mea loa ole. Olelo ana kēia 'ōlelo, ia mea he nui, e like me ka manawa i olelo ia, symmetric encryption algorithms. Ka mea, noho wale nō.

ʻO kēia ao nei: ke ano o ka encryption algorithms

Like pili ana i ka 'ohana ka palekana o ke anamanaʻoʻikepili ma o ka o kēia au nei, ka mea e hoi e noho ana ma luna o nā lā ka wā kamepiula' ē aʻe i ike ole ia i kanaka. Not e hōʻike i ka nui o pepa i laila 'o ia i ka alchemists, a me ka ia Temepela, imi e hūnā i nā hāʻina o nā haʻawina oiaio i ike ia ia i ka ike, ka mea, o ke kumukuai hoomanao ana mahope mai o ka muli o ka' ōlelo pilikia i wale worsened.

A laila, paha, o ka loa ua pono-ike lima kūlana kiʻekiʻe i ke kapa i ka Kelemānia cipher mīkini iloko o ka Apana World i kapaia "Enigma", i unuhi 'ia English ia hoʻi, "pohihihi." Hou, keia mea he hana o ana i ka symmetric encryption algorithms i hoʻohana ', i ka i loko o ka i mea e shifrovschik a me cryptanalysts ike i ke ki (algorithm), mua haawi e hūnāʻikepili.

I kēia lā, e like me ka cryptosystem ua i hoʻohana na wahi a pau. Ka loa ana hoʻohālike hiki ke noonoo, no ka laʻana, AES256 encryption algorithm, i mea no ka lahui hae. Mai ke kuanaʻike o ka kamepiula terminology, ka mea e leie aku oe i ka hoʻohana 'ana i kekahi ki lōʻihi o 256'āpana. I mau, laekahi encryption algorithms i loa like, a mahele ae la ia lakou hiki e pakike i loko o nā pā papa: symmetric a me ka asymmetric. Ka mea, e, ke kaumaha ma muli o ka mākaʻikaʻi wahi, e hoʻohana nui kaiāulu. Ke koho ana o ka encryption algorithm hilinaʻi nui ma luna o ka hana a me ke ano o ke ola 'ike i loko o kona kikokikona ano. Akā, ka mea i ka likeʻole ma waena o lākou?

Symmetric a asymmetric encryption algorithms: aha ka ke koena unuhi

Ano, e ka ike i ke ano o ke kumu likeʻole ma waena o ia mau nenoai, a me nā loina ma luna i ka nānā 'ana i ko lakou mau palapala noi i ka hoʻomaʻamaʻa. E like me ka maopopo, e pili ana i ka geometrical manaÿo o ka symmetry a me asymmetry ka encryption algorithms. He aha ka mea, 'o ia hoʻi kēia manawa, a e e wehewehe.

Symmetric encryption algorithm Des, hoʻomohala i ka 1977, hoʻohuʻu ke ola ana o ka hookahi kī i ua supposedly ike no na aoao elua e pili ana. ka mea, he mama i ka hoʻohana 'ana ka ike i ke kī, hahao ia i loko o nä hana kilokilo, e heluhelu i ka mea meaningless kau o nā huapalapala, e lawe mai ana ia, no laila, e'ōlelo aku, i loko o ka readable palapala.

A me ka mea mau i ka asymmetric encryption algorithms? Aia mau ki elua i hoʻohana ', i mea e encode i ka palapala hōʻike hoʻohana kekahi e decrypt i ka maʻiʻo - ka' ē aʻe, a me ia mea,ʻaʻole e pono ia ia i ka ia, a ma ka mea ia manawa e noho ana i loko o ka helu kuʻina a me ka ho omńkalakala aoao. No kela a me keia o ia wale nō kekahi. Penei, he degere kiʻekiʻe loa o nā ki ke hoʻokoe ', mai ke komoʻana o ka lima kolu. Eia naʻe, ma muli o ka he kulana, he nui hackers aihue i kēia 'ano o kekahi mau pilikia a me ka mea ole. ʻO kekahi mea - e loaʻa pono kī ('ōlelo koʻikoʻi akula olelo ana, he password), i ka pono, e decrypt i nā ikepili. Akā koho hiki malaila e ai na mea he nui e hiki ai ka loa kēia kamepiula, e kō ia no kekahi mau makahiki. E like me ka'ōlelo, i kekahi o ko ke ao nei ka na kamepiula nenoai e hack ke kōkua o ke ia ia, a loaa ka mea ua kapaʻia ka "wiretapping" hiki ole ole, a e e hiki i ka hoi ana mai oʻumi makahiki.

Ka loa pono-ike a mau hoʻohana encryption algorithms

Akā hoʻi i loko o ke kamepiula honua. He aha ma kaumaha kumu o encryption algorithms no ka hoomalu ana o ka 'ike ma luna o ka papa kahua o ka? Acaeoey o ke kamepiula a me ka' ike loea lawe lima?

Ma ka hapanui o nā'āina, no ka Mai de facto hae o AES cryptographic'ōnaehana ma muli o ka 128-iki kī. Eia naʻe, ma ka laua me ka mea, ua i kekahi manawa, hoʻohana algorithm RSA encryption, a eia nae i hai aku i ka encryption ka hoʻohana 'ana i ka lehulehu (lehulehu) ki aka o kekahi o ka loa ike loea. Kēia, incidentally, hoao ia e nā mea a pau i ke alakai akamai, mahope mai o ka'ōnaehana iho hilinaʻi nui ole wale ma luna o kaʻikepili encryption, akā, i ka malama ana o ka pono o ka 'ike. Like no ke kakahiaka nui kūpono 'ana, i ka i pili i ka Des encryption algorithm, ia mea hopelessly OOAOAaXUEE, a me ka ho'āʻo' ana e puku ia i ua hoʻomaka 'ana i ka 1997. Ua Ua laila, ma muli o ka mea, he hou a me ka holomua (Pae holomua Lālā) encryption maʻamau AES (mua me 128-iki ua ki nei, a laila, - me ka 256-iki kī).

RSA encryption

Ano, ke kālele ana ma luna o ka RSA 'ike loea hou a pili i ka asymmetric encryption nenoaiu. Ina i kekahi kanaka e hoouna i kekahi 'ike hoʻopā'āluaʻia me keia algorithm.

E encrypt lawe mau i lawa ka nui helu o X a me Y, i laila mau hōʻailona lākou huahana Z, ua kapaia he Module. Eia kekahi extraneous i koho helu A, i satisfies keʻano: 1

He aha ka hana i ka wā i ka ukana? Ka mea i hoʻounaʻia paha ke he ciphertext, i hoʻokohu 'F, a me ka loiloi mua memo M, i ukali ia e exponentiation A multiplication Module a me Z: F = M ** A * (mod Z). Haumāna haʻawina kālā alodio laʻana mea e hoʻomaulia: M = F ** B * (mod Z). 'ōlelo koʻikoʻi akula olelo ana, a pau ana i kēia mau hana i hoemiia wale nō i ka hana o ka mana. Na ia mau rula hana hōʻoia a me ka hoʻokumu o ka mīkini inoa, akā, ua oi huikau ke helu kaulike 'aneʻi. E pakele ke alahulaʻana i ka mea hoʻohana i ka poo hōʻailona helu, ua mea e ole e hoakaka ia.

Like no ka hacking, ka RSA encryption algorithm 'alo i ka poʻe komohewa kokoke unsolvable hana: e ho omaulia i ke ki B. kēia theoretically hiki ke hana ia me ka hoʻohana' ana o ka loaʻa dala factoring (decomposition i loko o kumumea loiloi mua huahelu X a me Y), akā, i ka lā i ia mau mea, nolaila, o ka hana iho lilo ia i mea paʻakikī - ia mea nui,ʻaʻole hiki.

Des encryption

Eia ka kekahi, mau i ka loa efficient encryption algorithm me ka i kā mākou o 64'āpana aeie lōʻihi (pūʻulu) mai i nā manaʻoi wale 56. E like me i haiia ae maluna, i kēiaʻano hana i OOAOAaXUEE,ʻaʻole naʻe he lōʻihi lawa me ka hae cryptosystems i hoʻohana ma kaʻAmelika Hui Pūʻia, a hiki no i ka mea e malu ai oihana puolo.

Ke o Mānoa, no ka mea, o ka symmetric encryption e pili ana i keia ano o ka kaʻina o 48'āpana. A pau keia hana ua hoʻohana 'ia no ka 16 pōʻaiapuni o ka hāpana i ka 48 iki kī. Akā,! Nā pōʻaiapuni ma ka loina o ka hana e like, no laila, i keia wahi mea,ʻaʻole e hoʻomaulia i ka koi 'ia ka hana kī. No ka laʻana, kekahi o nā kamepiula 'ē aʻe loa mana i loko o ka United States oi aku ma mua o ka miliona dala, e "uhai" ka encryption i loko o kahi o ekolu a me ka hapalua hola. No ka machines ma lalo o ka papa o ka mea, e hoʻomaulia i ke kaʻina i maximizing kona hoike ana, ka mea lawe i hou aku 20 hola.

AES encryption

Eia hoi, ua i ka loa, he pono ole, a ua manaʻo a nei, invulnerable nenoaiu - ka algorithm AES encryption. He ua a ianoiyuaa a poe i ekolu XAaOOEN - AES128, AES192 a me AES256. Ke koho mua pili hou e hōʻoia i ka mālama 'ike o ka lawe lima manaʻo, a me ka lua o ka pae'āina ma ka pae kiʻekiʻe. Like hae, i ka'ōnaehana i kauoha aku nei i hoʻolaunaʻia ma ka makahiki 2002, a ua koke kona kākoʻo, ua kiʻiʻia ke Intel Inc, i produces unu lawelawe inoaia.

Kona o Mānoa, e like kekahi'ē aʻe symmetric encryption'ōnaehana ho'ēmi i kā i Me ka nānā 'ana ma luna o ka polynomial kivila e hoohalike ai a me ka computation ana me nā-dimensional huihui ikehu lā. E like me ka US aupuni, e crack i ka 128-iki kī lōʻihi decoder, a hiki i ka loa ke kālā, e lawe ma kahi o 149 trillion makahiki. I noi aku nei, e oko me ia he kupono kahi. I nā lako e i loko o ka haneri makahiki hope ua i ka ua lele akula nō, puaʻa heʻa ala me ka geometric Holomua, no laila, i ka oi aku e ole kuhihewa kakou, o ka nui no laila, e, e like me ka mea huli mai, ma laila nō encryption a me ka oi ma mua o ka poʻe i kaʻAmelika Hui Pūʻia kūkala i ka loa hoʻopale i ńlua ho opa ao.

Pilikia a me nā mea hoʻomaʻi a me ka decrypting

O ka holo ana, ke mea e kamailio e pili ana i nā mea hoʻomaʻi. Nei, he mau loa ai kekahi nā mea hoʻomaʻi, ransomware, a encrypts ka holoʻokoʻa paakiki pā hōkū a me ka Logical i pohā ma ka iho mailoko kamepiula, a laila, i ka luahi hookipa mai i ka palapala notifying ia e hoʻopā'āluaʻia nā waihona a pau a me ka decrypt ia hiki wale ke hoakaka ia mana ma hope o ka hookaa pali.

Ma keia hihia, ka mea nui loa, ka mea, ua hōʻike i kaʻikepili encryption AES1024'ōnaehana,ʻo ia hoʻi, ka lōʻihi o ke ki i noiʻEhā kā nui e na AES256, he helu o nā koho ka wā hulina, no ka mea decoder kūpono wale maoli he enormously.

A me ka hoopono ana mai o ka olelo o ka US aupuni ma ka manawa i loaʻa i decrypt i ke ki lōʻihi o 128'āpana, laila mea e pili ana i ka manawa ia e lawe i ka loaʻa i ka pāʻoihana no ka hihia o ke ki a me kona Lolina 1024 iki lōʻihi? Ua i laila, i kaʻAmelika Hui Pūʻia, a houia. No ka mea, ka mea i manaoio aku i kā lākou kamepiula cryptography nenoaiu mea hemolele. Auwe, ua kekahi poe akamai i (apparently, ka mua Soviet Union), a mamua o ka "luli" American postulates ma a pau.

Me nā mea a pau o keia, o ke alakai haku polokalamu o ka mea pale mū holapū lako polokalamu, a me ka "Kaspersky Keʻena", o ka poe akamai i ka poe i hana i ka "Kauka Web", ka hui ESET, a he nui 'ē aʻe honua luna wale shrug ko laua mau poohiwi, ka mea, e olelo aku nei, e decode ia he algorithm mea waleʻaʻohe kālā, akā, wahi a kekahi mea i loko o kēia e pili ana i i ole lawa manawa. O ka holo ana, ia oe e kelepona i ka Customer kākoʻo kaumaha e hoouna aku i ka hoʻopā'āluaʻia waihona, a ina he mea, ia mea i makemake loa ia ka mua - i loko o ka palapala i loko i ka mea i mua o ke encryption. Auwe, i ka mau Ikepili i ole haawi tangible hopena.

A ao i ua mai i ike

Pehea hiki au e olelo aku nei, ina mākou e huli i ka wā e hiki mai, me ka i hiki ke decipher i ka hala. Inā 'oe e nānā i ke ao nei o ko mākou Ka Wā Kaukani, ua hiki ke ike i ka mea hookahi no Roma ia Auguseto Gaio Yuliy Tsezar i loko o kekahi o kana mau palapala i hoʻohana symmetric encryption algorithms. Ua pono, ina oe e nana i ka Leonardo ka Vinci, no laila, a pau mea somehow,ʻaʻole ma luna iho, mai ka hoʻi ia i loko o ka mahinaʻai o ka cryptography, ua uhiia i ke kanaka i hookaakaaiaʻe kona ola me ke ano o ka paku o ka pohihihi, ua oi kona modernity no kenekulia.

Hiki i keia manawa, he nui kanaka e ole e hoʻomaha ai i ka ai-kapaia "Mona Lisa Smile," ma a he mea kekahi uʻi, i ke kālā no ke kanaka mea e hiki ke hoʻomaopopo. Incidentally, i loko o ke kiʻi me ka manao i kekahi mau huapalapala (i loko o ka maka o kaʻaʻahu, a no laila, ma luna o. D.) Ua nei ua loaʻa i maopopo hōʻike i nā mea a pau i kēia kekahi mua kekahi hoʻopā'āluaʻia ano akamai nui o ka 'ike i kēia lā, auwe, e lawe mai ole. Akā, ua i mai i oleloia i ka nāʻano likeʻole o ka nui-unahiʻole, i nā hale, a ua hiki ke hoohuli ae i ka hoomaopopo ana o na ke kālaikūlohea o ka manawa.

O ka holo ana, e haliu mai i ko wale no ka mea i loko o ka hapanui hoopii, ua hoʻohana i ka ai-kapaia "gula pauku", nae, a me ka mea, aole e haawi i ke ki i ka mea a pau i nui loa o ka ike, a ua manaoio paha mākou e i maopopo, a nalowale loa kekahi manao. Apparently, cryptography koe e e hana i ka mea hiki ole ka hailonaʻana o ka hana, e ike i ke kālā no encryption algorithms pinepine mai e hele i kekahi e like me ka pae'ōnaehana manawa o ke kahiko maikai ana. A, ina i keia la he mea nui maliuʻia nā loina o ka 'ike e malu, me ka poe i i hoʻohana i loko o ka wā kahiko, Eia naʻe, ua mau loa inaccessible a me ka incomprehensible.

A me kekahi hou mea. Aia ka he unspoken manaoio i hiki ole e unuhi ka hapanui o kahiko hāʻina o nā haʻawina no ka mea. D. A i haʻalele i nā ki i deciphering i ko lakou pili loa i malama i malu nā kaiapili e like me ka Freemasons, ka Illuminati, a no laila, ma luna o ka Temepela lākou mark 'aneʻi. He aha hiki mākou e olelo e pili ana i mea nō koe loa inaccessible waihona o ka Waikikana? Mai hoahu i ka papa kuhikuhiE clues i ka wā kahiko ma laila? i hāliu mai i ko na mea he nui akamai a hiki i keia mana o ka manaoio i ka Waikikana ka noonoo e aua ana i kēia 'ike mai ka lehulehu. Like ia paha ole,ʻaʻole ike. Akā, hoʻokahi mea mea no kaʻoiaʻiʻo - kahiko cryptography'ōnaehana i ole ala e emi iki mahope o ke (a paha no ka oi) ka poe i hoʻohana 'ia i loko o kēia lā ka kamepiula honua.

kahi o ka epilogue

Eia hoi ka mea e e olelo ana i loaʻa i ua noʻonoʻo,ʻaʻole a pau, ao ke ano o ka papa cryptographic nenoai a me nā 'ana i kūpono i ka mea hana. Ka mea o ia i loko o ka hapanui o na hihia makemake i ke alakai eiiieaena makemakika nā papakuhikuhi a me ka makana helu, mai a ka hapa nui o nā mea hoʻohana wale e hele poʻo milo. Pono e nana i ke kumu hoohalike o ke ano o ka RSA algorithm, e ike i na mea a pau e ae, e nana i ka hailona hou huikau.

Na ka papa kuhikuhiE mea - e maopopo, a puliki, no laila, e olelo aku, i loko o ka naʻau o ka mea. Pono, ina ua kamailio e pili ana i ka mea i ka laekahi nenoai, a kaumaha aku i ka hoahu anamanaʻo 'ike i loko o ke ala i mea ole i ka kaupalena helu o nā mea hoʻohana, he mea uuku i waeia. 'Oiai, he mea nui cryptographic nenoai, ka ia RSA a me Des algorithms i maopopo losing AES i Kekahi Mau'. Eia naʻe, loa laekahi noi 'ia no ka lā pu ole, ma waena o pae'ōnaehana nenoai, hoʻohana o AES (maoli ai ke kaumaha ma muli o ka palapala noi a me ka noonoo o kanaka). Akā, 'aneʻi ka ka "akeakea kuleana" evolution o keia cryptosystem, e kau iaʻo Iosepa, he nui loa, o ka oi aku kona Mamua, walawala ai. Akā, ma ka a pau, ma muli o ka mea i loaʻa i kēia lā, he nui nā mea hoʻohana e ole e hiki ole i ka maopopo i ka mea a ka cryptographicʻikepili encryption'ōnaehana, no ke aha la ka mea i pono, a pehea e hana.
