  • Publication number: 20220239463
    Abstract: The present invention concerns a method for confidentially processing the kinematic data of a vehicle (210), 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 (254) by the vehicle by means of a symmetric encryption algorithm using a secret key generated (251) by the vehicle. This secret key is encrypted (252) by the vehicle by means of a homomorphic asymmetric encryption algorithm by using the public key of a vehicle service provider (240). The data encrypted by means of the secret key, and the homomorphically encrypted secret key, are transmitted (253, 255) by the vehicle to an access point that transcrypts (261) them and transmits (262) the homomorphically encrypted data to a calculation platform (230).

  • Publication number: 20220238338
    Abstract: A method for forming SiGe-based regions with different Ge concentrations is provided. After defining the regions 1, 2 on a SOI substrate, a grating of masking patterns is formed on at least one region 2. After the epitaxial growth of a Ge-based layer in each of the regions, a first vertical diffusion is carried out. A second horizontal diffusion is then carried out such that the Ge diffuses beneath the masking patterns of the region 2. Thus, the region 2 has a Ge concentration that is lower than the Ge concentration of the region 1.
