Kubva Chivabvu 2020, kutengesa zviri pamutemo kweWD Bhuku Rangu ekunze madhiraivha anotsigira AES hardware encryption ine 256-bit kiyi kwatanga muRussia. Nekuda kwezvirambidzo zvemutemo, michina yakadai yaimbotengwa muzvitoro zvemagetsi zvekunze zvepamhepo kana pamusika we "grey", asi ikozvino chero munhu anogona kuwana dhiraivha yakachengetedzwa ine waranti yemakore matatu kubva kuWestern Digital. Mukukudza chiitiko ichi chakakosha, takasarudza kuita kanguva kapfupi munhoroondo uye kuona kuti Advanced Encryption Standard yakaonekwa sei uye nei yakanaka kwazvo kana ichienzaniswa nemakwikwi mhinduro.
Kwenguva yakareba, chiyero chepamutemo che symmetric encryption muUnited States yaive DES (Data Encryption Standard), yakagadziridzwa neIBM uye yakaverengerwa murondedzero yeFederal Information Processing Standards muna 1977 (FIPS 46-3). Iyo algorithm yakavakirwa pane zvinoitika zvakawanikwa panguva yekutsvagisa chirongwa kodhi-inonzi Lucifer. Musi waChivabvu 15, 1973, US National Bureau of Standards yakazivisa makwikwi ekugadzira chiyero chekunyorera kumasangano ehurumende, mubatanidzwa weAmerica wakapinda mujaho rekriptographic neyechitatu vhezheni yaLucifer, iyo yakashandisa yakagadziridzwa Feistel network. Uye pamwe chete nevamwe vakwikwidzi, zvakakundikana: hapana kana imwe yealgorithms yakaunzwa kumakwikwi ekutanga yakasangana nezvinodiwa zvakasimba zvakaitwa neNBS nyanzvi.
Ehe, IBM yaisangobvuma kukundwa: pakatanga makwikwizve musi waNyamavhuvhu 27, 1974, mubatanidzwa weAmerica zvakare wakatumira chikumbiro, ichipa shanduro yakavandudzwa yaLucifer. Panguva ino jeri rakanga risina chichemo chimwe chete: kuita basa rakakodzera pane zvikanganiso, IBM yakabudirira kubvisa kukanganisa kwose, saka pakanga pasina chekunyunyuta pamusoro. Sezvo akunda kukunda kukuru, Lucifer akachinja zita rake kuita DES uye rakaburitswa muFederal Register munaKurume 17, 1975.
Nekudaro, panguva yeruzhinji symposia yakarongwa muna 1976 kuti ikurukure iyo itsva cryptographic standard, DES yakashoropodzwa zvakanyanya nenyanzvi munharaunda. Chikonzero cheizvi kwaive shanduko dzakaitwa kune algorithm neNSA nyanzvi: kunyanya, kureba kwakakosha kwakaderedzwa kusvika 56 bits (pakutanga Lucifer akatsigira kushanda ne64- uye 128-bit makiyi), uye logic yemabhuroko ekubvumidza yakashandurwa. . Sekureva kwevanodhirofeta, "kuvandudzwa" kwaive kusingabatsiri uye chinhu chega icho National Security Agency yaivavarira nekuita shanduko yaive yekukwanisa kuona vakasununguka magwaro akavharidzirwa.
Nezvekupomerwa uku, komisheni yakakosha yakaumbwa pasi peSeneti yeUS, chinangwa chayo chaive chekuona chokwadi chezviito zveNSA. Muna 1978, mushumo wakabudiswa mushure mekuferefeta, iyo yakataura zvinotevera:
- Vamiriri veNSA vakapinda mukupedzisa kweDES chete zvisina kunanga, uye mupiro wavo waingobata shanduko mukushanda kwemabhuroko ekubvumidza;
- iyo yekupedzisira vhezheni yeDES yakave yakanyanya kupikisa kubira uye kuongororwa kwekriptographic pane yekutanga, saka shanduko dzaive dzakakodzera;
- hurefu hunokosha hwemabhiti makumi mashanu neshanu hwakakwana kune huwandu hwakawanda hwezvishandiso, nekuti kutyora cipher yakadaro kunoda supercomputer inodhura angangoita makumi emamiriyoni emadhora, uye sezvo varwi vemazuva ese uye kunyange nyanzvi dzekubira havana zviwanikwa zvakadaro, hapana chekunetsekana nacho.
Mhedziso dzekomisheni dzakasimbiswa zvishoma muna 1990, apo Israel cryptographers Eli Biham naAdi Shamir, vachishanda pane pfungwa yekusiyanisa cryptanalysis, vakaita chidzidzo chikuru che block algorithms, kusanganisira DES. Masayendisiti akagumisa kuti iyo nyowani yekubvumidza modhi yainyanya kurwisa kurwiswa kupfuura yekutanga, izvo zvinoreva kuti iyo NSA yakanyatso batsira kuvhara maburi akati wandei mune algorithm.
Adi Shamir
Panguva imwecheteyo, kudzikisira pakureba kwakakosha kwakava dambudziko, uye rakanyanya kuoma pane izvozvo, izvo zvakaratidzwa zvinogutsa muna 1998 nesangano reruzhinji Electronic Frontier Foundation (EFF) sechikamu chekuedza kweDES Challenge II, yakaitwa pasi pechirongwa cheRSA Laboratory. Supercomputer yakavakirwa zvakanangana kupaza DES, codenamed EFF DES Cracker, iyo yakagadzirwa naJohn Gilmore, co-muvambi weEFF uye director weDES Challenge chirongwa, naPaul Kocher, muvambi weCryptography Research.
processor EFF DES Cracker
Iyo sisitimu yavakagadzira yakakwanisa kubudirira kuwana kiyi kune yakavharidzirwa sampuli ichishandisa brute force mumaawa makumi mashanu nematanhatu chete, ndiko kuti, mumazuva asingasviki matatu. Kuti uite izvi, DES Cracker yaida kutarisa chikamu chimwe muzvina chezvese zvinogoneka musanganiswa, izvo zvinoreva kuti kunyangwe mumamiriro ezvinhu asina kunaka, kubira kwaizotora anenge maawa 56, ndiko kuti, asingapfuure mazuva gumi. Panguva imwecheteyo, mutengo weiyo supercomputer, uchifunga nezve mari yakashandiswa pakugadzira kwayo, yaingova 224 zviuru zvemadhora. Hazvina kuoma kufungidzira kuti nhasi zviri nyore uye zvakachipa kupaza kodhi yakadaro: kwete chete iyo hardware yakawedzera simba, asiwo nekuda kwekuvandudzwa kweInternet matekinoroji, hacker haafanirwe kutenga kana kurenda iyo. midziyo inodiwa - yakakwana kugadzira botnet yePC ine hutachiona.
Kuedza uku kwakaratidza zvakajeka kuti DES yakapera sei. Uye sezvo panguva iyoyo algorithm yakashandiswa munenge makumi mashanu muzana emhinduro mundima yedata encryption (maererano nefungidziro imwechete yeEFF), mubvunzo wekutsvaga imwe nzira wakawedzera kudzvanya kupfuura nakare kose.
Zvinetso zvitsva - makwikwi matsva
Kutaura chokwadi, zvinofanirwa kutaurwa kuti kutsvaga kwekutsiva kweData Encryption Standard kwakatanga panguva imwe chete nekugadzirira kweEFF DES Cracker: The US National Institute of Standards and Technology (NIST) kumashure muna 1997 yakazivisa kutanga kwe encryption algorithm makwikwi akagadzirirwa kuratidza "yegoridhe chiyero" chitsva chekriptosecurity. Uye kana mumazuva ekare chiitiko chakafanana chaiitwa chete "kuvanhu vedu," saka, tichifunga nezvechiitiko chisina kubudirira chemakore makumi matatu apfuura, NIST yakasarudza kuita kuti makwikwi avhurwe zvachose: chero kambani uye chero munhu angatora chikamu iyo, zvisinei nenzvimbo kana mugari.
Iyi nzira yakazviruramisa kunyangwe padanho rekusarudza vanyoreri: pakati pevanyori vakanyorera kuti vatore chikamu mumakwikwi eAdvanced Encryption Standard vaive nemukurumbira pasi rose cryptologists (Ross Anderson, Eli Biham, Lars Knudsen) uye makambani madiki eIT anoshanda necybersecurity (Counterpane) , uye makambani makuru (German Deutsche Telekom), uye masangano edzidzo (KU Leuven, Belgium), pamwe chete nekutanga-ups uye mafemu maduku ayo vashoma vakanzwa kunze kwenyika dzavo (somuenzaniso, Tecnologia Apropriada Internacional kubva kuCosta Rica).
Sezvineiwo, panguva ino NIST yakabvumidza zviviri chete zvakakosha zvekutora chikamu algorithms:
- iyo data block inofanira kunge yakagadziriswa saizi ye128 bits;
- iyo algorithm inofanira kutsigira hukuru hutatu hunokosha: 128, 192 uye 256 bits.
Kuwana mugumisiro wakadaro kwaiva nyore, asi, sezvavanotaura, dhiyabhorosi ari mumashoko: paiva nezvimwe zvakawanda zvechipiri zvinodiwa, uye zvakanga zvakaoma zvikuru kusangana nazvo. Zvichakadaro, zvaive pahwaro hwavo kuti vaongorori veNIST vakasarudza vakwikwidzi. Heano maitiro ayo vakakumbira kukunda vaifanira kusangana nawo:
- kukwanisa kumira chero cryptanalytic kurwiswa kunozivikanwa panguva yemakwikwi, kusanganisira kurwiswa kuburikidza nechitatu-bato nzira;
- kusavapo kwemakiyi asina simba uye akaenzana encryption (yakaenzana inoreva makiyi ayo, kunyangwe aine misiyano yakakura kubva kune mumwe nemumwe, anotungamira kune akafanana ciphers);
- iyo encryption yekumhanyisa yakagadzikana uye yakangofanana pamapuratifomu ese aripo (kubva pa8 kusvika pa64-bit);
- optimization kune multiprocessor masisitimu, tsigiro yekufananidza kwekushanda;
- zvishoma zvinodiwa pahuwandu hwe RAM;
- hapana zvirambidzo zvekushandisa mumamiriro akajairwa (sechikonzero chekuvaka hashi mabasa, PRNGs, nezvimwewo);
- Chimiro chealgorithm chinofanira kuve chine musoro uye chiri nyore kunzwisisa.
Pfungwa yekupedzisira ingaita seisinganzwisisike, asi kana iwe ukafunga nezvazvo, zvine musoro, nekuti yakanyatsorongeka algorithm iri nyore kuongorora, uye zvakare zvakanyanya kuoma kuviga "bookmark" mairi, nerubatsiro rwe. iyo mugadziri anogona kuwana isina muganho kuwana kune encrypted data.
