Vatsvagiri kubva kuCatholic University yeLeuven vakagadzira nzira yekurwisa kiyi encapsulation mechanism SIKE (Supersingular Isogeny Key Encapsulation), iyo yakabatanidzwa mumafainari emakwikwi e-post-quantum cryptosystems akaitwa neUS National Institute of Standards and Technology (SIKE). akaverengerwa uye akati wandei ekuwedzera algorithms akapfuura makuru ekusarudza matanho, asi akatumirwa kuti adzokororwe kubvisa zvirevo zvisati zvaendeswa kuchikamu chezvinokurudzirwa). Iyo yakarongwa nzira yekurwisa inobvumira, pakombuta yega yega, kudzoreredza kukosha kwekiyi yakashandiswa encryption zvichibva paSIDH (Supersingular Isogeny Diffie-Hellman) protocol inoshandiswa muSIKE.
Kuitwa kwakagadzirira-kuitwa kweiyo SIKE yekubira nzira yakaburitswa sechinyorwa cheMagma algebraic system. Kuti udzore kiyi yakavanzika yakashandiswa encrypt yakachengeteka network masesisheni, uchishandisa iyo SIKEp434 (level 1) parameter yakaiswa pane imwechete-core system, zvakatora 62 maminetsi, SIKEp503 (level 2) - 2 maawa 19 maminetsi, SIKEp610 (level 3) - Maawa masere nemaminitsi gumi nemashanu, SIKEp8 (chikamu 15) - maawa makumi maviri nemaminitsi makumi matatu nemanomwe. Zvakatora 751 uye 5 maminetsi, zvichiteerana, kugadzirisa emakwikwi mabasa $IKEp20 uye $IKEp37 akagadzirwa neMicrosoft.
Iyo SIKE algorithm yakavakirwa pakushandiswa kwesupersingular isogeny (inotenderera mune supersingular isogeny graph) uye yaifungidzirwa neNIST semumiriri wekumisikidzwa, sezvo yaisiyana kubva kune vamwe vavhoti mudiki kiyi saizi uye tsigiro yekusavimbika kwepamberi (kukanganisa imwe. zvemakiyi enguva refu hazvibvumidze kuvharwa kwechikamu chakambobvumwa) . SIDH ianalogue yeDiffie-Hellman protocol yakavakirwa pakutenderera mune supersingular isogenic graph.
Iyo yakadhindwa SIKE yekupwanya nzira yakavakirwa paiyo 2016 yakarongwa adaptive GPST (Galbraith-Petit-Shani-Ti) kurwisa supersingular isogenic kiyi encapsulation masisitimu uye inoshandisa kuvepo kwediki isiri-scalar endomorphism pakutanga kwe curve, inotsigirwa nekuwedzera. ruzivo nezve torsion point inofambiswa nevamiriri vanodyidzana mukuita kweprotocol.
