Abstract
The present invention concerns a method for confidentially processing the kinematic data of a vehicle, in particular a method for classifying this data in order to determine the driving style of the vehicle while respecting the confidentiality of the data in question. The data is encrypted by the vehicle by means of a symmetric encryption algorithm using a secret key generated by the vehicle. This secret key is encrypted by the vehicle by means of a homomorphic asymmetric encryption algorithm by using the public key of a vehicle service provider. The data encrypted by means of the secret key, and the homomorphically encrypted secret key, are transmitted by the vehicle to an access point that transcrypts them and transmits the homomorphically encrypted data to a calculation platform. The platform performs the confidential processing operation in the homomorphic domain and transmits the homomorphically encrypted results to the server of the vehicle service provider.
