Patent

CA 2452419

The invention relates to means for protecting information systems against a nonauthorised intrusion. Said invention makes it possible to form a pass- through circuit for protecting a data distributed processing. The access to a computer system being obtained on a user device and on a server for the data distributed processing, a system of internal and external keys based on secret keys received from a centre for certifying, forming and distributing keys is formed. Secret internal single-use keys for a symmetrical encryption mode used for data transmission, storage and processing are generated, and a connection request to a pre-selected server is sent from the user device to the certification centre. Open keys on which the external single-use keys for symmetrical encryption mode are generated are received. For transmission to the server, sent information is encrypted by using a stochastic coding involving the use of the external single-use keys. Said information is also encrypted using secret internal single-use symmetrical keys, processed, stochastically coded and sent to the user device.

L'invention concerne les moyens de protection des systèmes informatiques contre l'accès non autorisé. Elle permet de former un circuit de protection de bout en bout du traitement réparti de données. Au niveau du dispositif utilisateur et du serveur de traitement réparti de données, on accède au système informatique et l'on forme un système de clés internes et externes sur la base de tables de clés secrètes reçues depuis un centre de certification, de formation et de distribution des clés. On génère des clés internes à usage unique destinées au mode de chiffrage symétrique pendant la transmission, le stockage et le traitement des données. Depuis le dispositif utilisateur, on envoie au centre de certification une demande de connexion à un serveur préalablement choisi. On obtient les clés publiques sur la base desquelles on génère des clés externes à usage unique destinées au chiffrage symétrique. Pour la transmission au serveur, on chiffre les informations transmises en utilisant le codage stochastique employant les clés secrètes à usage unique. Ces données sont soumises à un chiffrage supplémentaire utilisant les clés symétriques internes à usage unique puis traitées, soumises au codage stochastique et transmises au dispositif utilisateur.
