Ofufuza ku Catholic University of Leuven apanga njira kuukira kiyi encapsulation limagwirira SIKE (Supersingular Isogeny Key Encapsulation), amene anaphatikizidwa mu omaliza a pambuyo quantum cryptosystems mpikisano unachitikira ndi US National Institute of Standards and Technology (SIKE). adaphatikizidwa ndi ma aligorivimu owonjezera omwe adadutsa magawo akulu osankhidwa, koma adatumizidwa kuti awonedwenso kuti athetse ndemanga asanasamutsidwe ku gulu lolimbikitsidwa). Njira yowukira yomwe akufunsidwa imalola, pakompyuta yanu yokhazikika, kupezanso mtengo wa kiyi yomwe imagwiritsidwa ntchito pobisalira potengera protocol ya SIDH (Supersingular Isogeny Diffie-Hellman) yomwe imagwiritsidwa ntchito mu SIKE.
Kukhazikitsa kokonzeka kwa njira yozembera ya SIKE kwasindikizidwa ngati script ya Magma algebraic system. Kuti mubwezeretsenso kiyi yachinsinsi yomwe imagwiritsidwa ntchito kubisa magawo otetezedwa a netiweki, pogwiritsa ntchito SIKEp434 (level 1) parameter yokhazikitsidwa pa single-core system, zidatenga mphindi 62, SIKEp503 (level 2) - 2 hours 19 minutes, SIKEp610 (level 3) - Maola 8 mphindi 15, SIKEp751 (level 5) - maola 20 mphindi 37. Zinatenga mphindi 182 ndi 217, motero, kuthetsa ntchito za mpikisano $ IKEp4 ndi $ IKEp6 zopangidwa ndi Microsoft.
SIKE aligorivimu idakhazikitsidwa pakugwiritsa ntchito supersingular isogeny (yozungulira mu supersingular isogeny graph) ndipo idawonedwa ndi NIST ngati ofuna kuyimitsidwa, popeza idasiyana ndi ena osankhidwa pakukula kwake kakang'ono kwambiri komanso kuthandizira chinsinsi chakutsogolo (kusokoneza chimodzi). za makiyi aatali salola kumasulira kwa gawo lomwe linalandidwa kale) . SIDH ndi analogue ya Diffie-Hellman protocol yozikidwa pa kuzungulira mu supersingular isogenic graph.
Njira yosweka ya SIKE idakhazikitsidwa ndi 2016 yomwe ikufuna kusintha GPST (Galbraith-Petit-Shani-Ti) kuukira kwa supersingular isogenic key encapsulation mechanisms ndipo imagwiritsa ntchito kukhalapo kwa endomorphism yaying'ono yopanda scalar kumayambiriro kwa curve, mothandizidwa ndi zina. Zambiri zokhudzana ndi malo ozungulira omwe amafalitsidwa ndi othandizira omwe akulumikizana ndi protocol.
