  • Patent number: 10313855
    Abstract: The present invention relates to a method to manage subscriptions in a provisioning server (PS) able to communicate with a Hardware Security Module (HSM) having an HSM key (K). Said method being such that the HSM comprising a load and a reload function, the secure device key ((Ke1)K) and the storage key ((Ks)K) as encrypted and stored are provided (S1) to one of said functions, said functions outputting, the storage key ((Ks)Ke1)K) encrypted using the provided secure device (SE1) key (Ke1) and the HSM key K, and an APDU_putkey command ((APDU_PUTKEY((Ks)Ke1))Ke1), encrypted using the provided secure device (SE1) key (Ke1), to put the retrieved storage key ((Ks)Ke1) also encrypted using the provided secure device key (Ke1), the storage key as previously stored ((Ks)K) is overwritten (S6) with the storage key (((Ks)Ke1)K) encrypted using the secure device key (Ke1) and the HSM key (K) returned by the function.

  • Publication number: 20140379370
    Abstract: A system for making safe the conduct of a succession of ordered steps. The succession of steps being applied to transform it to a mobile physical entity. The system comprises a database for inputting and storing the succession of steps, at least one step being associated with at least one prior step. An identification device identifies the physical entity in a zone of conduct of a step in progress. A terminal displays the successive steps. A server verifies that each prior step associated with the step in progress has been previously validated and manages discharge of the physical entity from the zone of the conduct of the step in progress. A sensor validates the realization of the step in progress by an operator associated with the step in progress. A storage device stores each validation.
