La soci\u00e9t\u00e9 Google a publi\u00e9 un ensemble ouvert de biblioth\u00e8ques et d'outils avec une mise en \u0153uvre d'un syst\u00e8me de chiffrement homomorphe complet, permettant de traiter des donn\u00e9es sous forme chiffr\u00e9e, qui ne figurent sous aucune forme ouverte \u00e0 aucun des stades de calculs. L'outil permet de cr\u00e9er des programmes pour des calculs confidentiels, capables de travailler avec des donn\u00e9es sans d\u00e9chiffrement, y compris pour ex\u00e9cuter des op\u00e9rations math\u00e9matiques et des op\u00e9rations simples sur des cha\u00eenes de caract\u00e8res en donn\u00e9es chiffr\u00e9es. Le code du projet est \u00e9crit en C++ et est distribu\u00e9 sous la licence Apache 2.0. <\/p>\n

Contrairement au chiffrement de bout en bout, le chiffrement homomorphe, en plus de prot\u00e9ger les transmissions de donn\u00e9es, permet le traitement des donn\u00e9es sans leur d\u00e9chiffrement. Par homomorphisme complet, on entend la possibilit\u00e9 d'ex\u00e9cuter des op\u00e9rations d'addition et de multiplication sur des donn\u00e9es chiffr\u00e9es, \u00e0 partir desquelles toutes sortes de calculs arbitraires peuvent \u00eatre r\u00e9alis\u00e9s. En sortie, un r\u00e9sultat chiffr\u00e9 est produit, analogue \u00e0 ce qui serait obtenu par le chiffrement du r\u00e9sultat de ces m\u00eames op\u00e9rations sur les donn\u00e9es originales. <\/p>\n

Le traitement des donn\u00e9es dans le cadre du chiffrement homomorphe consiste \u00e0 ce que l'utilisateur chiffre les donn\u00e9es et les transmette pour traitement \u00e0 un service tiers sans r\u00e9v\u00e9ler les cl\u00e9s. Ce service effectue les calculs demand\u00e9s et g\u00e9n\u00e8re un r\u00e9sultat chiffr\u00e9, sans avoir la possibilit\u00e9 de d\u00e9terminer avec quelles donn\u00e9es il travaille. L'utilisateur d\u00e9chiffre les donn\u00e9es fournies \u00e0 l'aide de ses cl\u00e9s et obtient le r\u00e9sultat sous forme ouverte.

\"Google<\/center> <\/p>\n

Parmi les domaines d'application du chiffrement homomorphe figurent la cr\u00e9ation de services cloud pour des calculs confidentiels, la mise en \u0153uvre de syst\u00e8mes de vote \u00e9lectronique, la cr\u00e9ation de protocoles de routage anonymis\u00e9s, le traitement de requ\u00eates sur des donn\u00e9es chiffr\u00e9es dans des SGBD, et l'entra\u00eenement confidentiel de syst\u00e8mes d'apprentissage automatique. <\/p>\n

Par exemple, le chiffrement homomorphe sera utile dans les applications m\u00e9dicales qui pourront recevoir des informations confidentielles des patients sous forme chiffr\u00e9e et permettre aux professionnels de la sant\u00e9 de r\u00e9aliser des analyses et d'identifier des anomalies sans d\u00e9chiffrer. Le chiffrement homomorphe peut \u00e9galement aider dans la recherche \u00e9tudiant le lien entre les maladies et certaines mutations g\u00e9n\u00e9tiques, n\u00e9cessitant l'analyse de milliers d'\u00e9chantillons d'informations g\u00e9n\u00e9tiques. <\/p>\n

Une caract\u00e9ristique distinctive de l'outillage publi\u00e9 est la possibilit\u00e9 de cr\u00e9er des programmes pour le traitement de donn\u00e9es chiffr\u00e9es, en utilisant des approches de d\u00e9veloppement standard en C++. Gr\u00e2ce au transpileur fourni, le programme en C++ est transform\u00e9 en un dialecte sp\u00e9cial FHE-C++ capable de fonctionner avec des donn\u00e9es chiffr\u00e9es.
