Hiʻona o kēia 'ōlelo nenoai

Ma mua kilohi, këia mau manaÿo i mea synonymous, akā, ka mea, i loa kekahi mau manaʻo.

Cipher mea he ano o ka hoʻololi 'ana i' ike i ka mea e mālama ia mai nesanktsionnovanih mea hoʻohana. 'Epekema e Haʻawina i nā kiʻina hana a me kaʻikepili encryption epekema kapa cryptography. It E e kaulana i Hawaiʻi nei ma ka entrenched cryptography kekahi hoʻokahi wale nō koa hua'ōlelo: kaʻenemi hoouka, kuhi, etc. - ka mea pololei noonoo i ke ano o ka pili manaÿo. Eia naʻe, koa terminology, ma muli o ka manawa "kivila" i mea e hana ai me kaʻimi naʻauao cryptography, no ka mea, i loko o nā makahiki ua loaʻa helu kuʻina kumumanaʻo - he nui scientific kahua i haʻawina a me ka hoʻomōhala ana i ki ina hana like o ka 'ike' ohana ka palekana mai ka hanana o ka huikau ka hewa ma ka 'ōlelo kaha. No laila, i ka i ana "helu kuʻina - mea he ano o ka encryption" mea he misnomer.

Hoʻopā'ālua a me ka encryption e pili loa ua hoʻopili, akā, kēlā a mau keʻano o ka hanaʻana i kona mau manao. ike helu kuʻina ua lawe mai i ka mea e hana i ka 'ike e like me kekahi mau rula i loko o ka palapala kupono no ka EYI ma luna o kekahi Kanal. Na kāna mau 'ōlelo o kekahi hoʻopā'ālua'ōnaehana o ka makemakika notation i hoʻopaʻa' ia e lauana, ma muli ia i kekahi ke loaa i kekahi helu o okoa nā loina. Nō kāu, na nā loina ho i kaula o aeaie 'Aʻohe hualoaʻa a me ka poʻe (ia i hoʻopaʻa' ia mea ma kona ano maoli, i ka wa i hiki a ho'āhu 'ike me nā kamepiula' ē aʻe e hoʻohana).

ʻikepili encryption - he ala o ka hoʻololi 'ana i' ike i ka AI ka palekana i ka ke aliiwahine ke kula. Pela, ua hoʻopā'āluaʻia ka memo no laila, i ka mea lilo incomprehensible, a ua hoopai karaima - e noho hala ole, a hiki ma hope o ka hoolilo ana o ke kamailio ana o ka wahi, i hiki ke loli ma ka leo. Helu kuʻina 'ike e emi i ke ano o ka kikokikona me ke kaupalena helu o nā huapalapala (' o ia hoʻi, helu kuʻina E e pono ai), a e huai ae a me ka pololei hewa ma ka EYI a me ka pūnaewele o ka 'ike (helu kuʻina E e corrective).

Nolaila, ina e makemake e hele i ka 'ike ma luna o ka kekahi loulou, no laila ia i ka auoiaea e loaa ka ike loea malū' ike pono i ka hui pu iho la laua i ka huli ana kaʻina hana, oia hoi:

- Aoaao memo kekahi helu'ōnaehana (kekahi manawa lawa hoohuliia i loko o ka aeaie'ōnaehana notation, akā, ma laila nō kekahi, e laʻa me, binomial, fibonachieva etc.);

- Encrypt memo (ka mea, he ākeaʻano o ka encryption ki ina hana like, mai ka paa ana o nā loina hiki kahiko);

- 'Oi hoʻopā'āluaʻia memo e e encoded ai me ia auaiaea ka memo e uniquely decoded;

- decode ka memo pono kuhikuhi a me ka pololei hewa e hana ana i EYI o ka memo;

- Decrypt i ka'ōlelo, e like me ka encryption lawe mai (no ka mea mea i hoʻounaʻia, a pa alima pono aelike mua encryption ina hana). E like me ka rula, ua hana oia i kekahi mau iaoia, a me ka "kī". Ke kī o ka huapalapala oʻikepili wā i ka papa huli ana o ka ai iiiaanoaa o cipher hou ';

- 'Oi memo hoolilo mai o ka loaa ana helu'ōnaehana i ka mua.

Ke'ī mai, i ka hoomalu a me ka pololei EYI o ka 'ike pono e ka hailona o ka hana. Kēia manawa ka, ikaika kamepiula enehana he nui simplifies kēia kaʻina hana, akā, ia mea i mau mea hiki e decrypt i ka olelo, o ka oi aku ina ke ki meaʻikeʻole i ke kōkua o ka 'enehana. Aie i na nā pilikia ma kaha o ka 'ike i ke nānaina, no laila, hoʻohana ua helu kuʻina i kūpono i hiki ke huai ae a me ka hooponopono i ka hewa.

No laila, ma o ka palapala Kanal ho'īli memo. Ka memo loaa, kulana kupono paha no ka parity o ka helu o nā huahelu: ina ka helu mea i huahelu i e ka mea mahuʻi e loaʻa nāʻaʻohe hewa, a me ka wā omńkalakala i hoolei aku i ka hope huahelu. Inā ka helu o nā huahelu mea ōlaʻi, hoouna aku la i ka olelo me ka wahaheʻe. Ke keakea ana o keia iaoia mea i mea e leie aku oe i wale huai ae hewa ole? Ee ia lakou, oiai ka repetition kuhi mea ole wale huai ae akā, i pololeiʻiʻo nō ia hewa.

Penei, i kela mea keia mea o na kēia mau ki ina hana like o ka helu kuʻina kona drawbacks, naʻe, i kēia mau kiʻina hana pāʻani he nui loa i ka helu kuʻina kumumanaʻo, aʻo ke kumu o ke kūkuluʻana i ka nui, hemolele loa nā loina. I ko makou manawa, e hoʻohana i ka Hamming nā loina, Nagoya, Reed -Myullera, Hadamard, a pela aku ..

KŘpa a ciphers pehea e hoʻopale ike mai ke aliiwahine ke kōkua o ia hoʻi, he mea mau aoao ma ka i 'oe hiki classify ciphers. Nō kāu, i ke kumu o Mea Maluna ua kuhi:

he) kaupalena hana ciphers;

b) ciphers mau ana o ka lehulehu-ki;

c) nā loina-kaʻana like me ka mea ponoi kī.

I ka makahiki 1963, i ka American mathematician Klod Shennon ka hoʻohana 'ana i ke ano ki ina hanaʻo ia? Ac? Noiʻi cipher mathematically kākoʻo i loko o nā mea a pau panina ciphers like typical eiiiiiaiou i na kēia mau ano o ka encryption me nā loina a me nā ciphers hoʻohuihui hoopuehu.

Hōʻuluʻulu manaʻo cipher lakou hoopuehu mea e redistribute redundancy kumu a mea i loko o kekahi mau wahi plaintext. No keia mea, me ka hakahaka o ka finite helu o ka oihana mua P, a mea he ike ki. Ke'ī mai, i ka helu o ka hiki ki mea like ia P.

I ka deciphered hoʻohana 'ana inverse hakahaka. Oia encryption, aole nae ia aʻole e pili mai ka alapine (frequency) o ka palapala, akā, hūnā i ke alapine (frequency) o bigrams, trigrams, a pela aku .. ka pā o ka cipher paʻipaʻiʻia ai e ka i ka pili ma waena o ke ki, a me ka encryption kikokikona e hana ai luna 'like hiki. Maikaʻi hoʻohana no ka hakahaka huahelu o kekahi mau hōʻailona o ka memo Hawaiʻi, e like nae ka mea hiki aku ai i ka mea i ke ki lilo nui ana.

Kukulu i kēia cryptology like me ka 'epekema ua muli ma ka totality o na mea a me ka manaÿo o ka makemakika, ke kālaikūlohea, ike kumumanaʻo , a pela aku .. naʻe, hoʻowahāwahā i ka ka manaʻo pohihihi, ua hoʻomano hoʻohana i ka nui o kaʻimi naʻauao E hana' ia cryptology i kela la i keia ola ana, e like me ea pepa, e-mail, kapa uku nenoai, a me ka hoike o ka 'ikepili i, lolouila ke koho ana kekahi, a pela aku ..
