  • Publication number: 20240080190
    Abstract: A system includes two or more communication devices. Each device includes a dedicated SDR chip with a dedicated key generator to generate a secret key shared by the two SDR chips using a physical unclonable function PUF that takes as an input configuration data and produces an output. In the dedicated key generator of each SDR chip, the PUF takes as an input configuration data and produces an output identical for the two SDR chips, that is the shared secret key or a seed to derive it. The configuration data is unique to each SDR chip, dependent on physical random factors introduced during manufacture of the SDR chip, and is adapted for the respective key generator to generate the shared secret key.

  • Publication number: 20240028703
    Abstract: A system for actively monitoring and securing a CDI. The system comprises a TEE implementing one or more monitoring policy rule for ruling the active monitoring of the CDI. The system further comprises an IC comprising one or more monitoring device for monitoring the CDI at a corresponding monitoring tapping point delivering a corresponding monitoring information element. The IC is configured for providing to the TEE a monitoring information based on the monitoring information element. The IC is subordinated to the TEE. The one or more monitoring device is configured by the TEE responsive to the implementation of the one or more monitoring policy rule.
