Abstract
The invention relates to a method and a system for computer-assisted maintenance of a device to be maintained, comprising a storage in a first system, which storage is implemented progressively when in use an operating system comprising the device to be maintained, of operational data associated with the said operating system. For a maintenance processing method, which is to be implemented by the second system () by applying a processing algorithm () to a set of operational data, the maintenance system uses a homomorphic or partially homomorphic cryptosystem () to obtain a modified maintenance processing algorithm () 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 ((D)) by a means of a cryptosystem encryption method (), and a second subset of plain data (D) from the said set of operational data.
