Les chercheurs ont r\u00e9cemment introduit un nouveau concept dans le domaine de la cryptographie, appel\u00e9 cryptage homomorphique hybride (HHE), qui combine la cryptographie sym\u00e9trique et le cryptage homomorphique (HE). Le HHE permet le cryptage local des donn\u00e9es \u00e0 l’aide d’un sch\u00e9ma de cryptage sym\u00e9trique et l’externalisation des donn\u00e9es crypt\u00e9es vers le nuage, o\u00f9 elles peuvent \u00eatre transform\u00e9es en cryptogrammes homomorphes sans \u00eatre d\u00e9crypt\u00e9es.<\/span><\/p>\n

Les scientifiques d’HARPOCRATES ont pr\u00e9sent\u00e9 \u00e0 la conf\u00e9rence Securecomm 2022 une nouvelle approche des services en nuage respectueux de la vie priv\u00e9e, rendue possible par le transfert des op\u00e9rations les plus co\u00fbteuses de l’HE vers le nuage. Comme d\u00e9crit dans la publication \u00a0\u00bb Symmetrical Disguise : Realizing Homomorphic Encryption Services from Symmetric Primitives \u00ab\u00a0, nos chercheurs se sont attel\u00e9s \u00e0 la t\u00e2che de concevoir un protocole cryptographique s\u00e9curis\u00e9 bas\u00e9 sur HHE, en montrant comment il peut \u00eatre utilis\u00e9 comme \u00e9l\u00e9ment principal d’un protocole qui permet aux analystes de collecter des donn\u00e9es \u00e0 partir de sources multiples et de calculer des fonctions sp\u00e9cifiques sur ces donn\u00e9es en pr\u00e9servant la vie priv\u00e9e.<\/span><\/p>\n

Ce d\u00e9veloppement open source permet \u00e0 la communaut\u00e9 des chercheurs et \u00e0 l’industrie dans le domaine de la cryptographie d’assurer une confidentialit\u00e9 efficace dans le stockage et le traitement des donn\u00e9es. En d\u00e9montrant comment le chiffrement homomorphe peut \u00eatre utilis\u00e9 dans des sc\u00e9narios r\u00e9alistes gr\u00e2ce \u00e0 la conception d’un protocole s\u00e9curis\u00e9, les chercheurs de HARPOCRATES repoussent les limites du chiffrement homomorphe.<\/span><\/p>\n
