Title
(EN) METHOD AND SYSTEM FOR COMPUTER-ASSISTED MAINTENANCE
(FR) PROCÉDÉ ET SYSTÈME DE MAINTENANCE ASSISTÉE PAR ORDINATEUR
Abstract
(EN)
The invention relates to a method and a system for computer-assisted maintenance of a device to be maintained, comprising storage in a first system, which storage is implemented as and when an operating system comprising the device to be maintained is in use, of operational data associated with the operating system. For a maintenance processing method, which is to be implemented by the second system (8) by applying a processing algorithm (38) to a set of operational data, the maintenance system uses a homomorphic or partially homomorphic cryptosystem (28) to obtain a modified maintenance processing algorithm (40) which makes it possible to obtain an item of predictive or corrective maintenance information in encrypted form, from a set of protected operational data comprising a first subset of encrypted operational data ((D1)H), by means of a cryptosystem encryption method (28), and a second subset of plain data (D2) from the set of operational data.

L'invention concerne un procédé et un système de maintenance assistée par ordinateur d'un dispositif à maintenir, comportant une mémorisation dans un premier système, mise en œuvre au fur et à mesure de l'exploitation d'un système en exploitation comportant le dispositif à maintenir, de données opérationnelles associées audit système en exploitation. Pour un traitement de maintenance, à mettre en œuvre par le deuxième système (8) en appliquant un algorithme de traitement (38) sur un ensemble de données opérationnelles, le système de maintenance utilise un cryptosystème (28) homomorphe ou partiellement homomorphe pour obtenir un algorithme de traitement de maintenance modifié (40), qui permet d'obtenir une information de maintenance prédictive ou corrective sous forme chiffrée, à partir d'un ensemble de données opérationnelles protégées comportant un premier sous-ensemble de données opérationnelles chiffrées ((D1)H) par un procédé de chiffrement du cryptosystème (28), et un deuxième sous- ensemble de données (D2) en clair dudit ensemble des données opérationnelles.
