摘要： A method for dynamic management of a first level of verbosity of a component defined in a data network, the data network having a control centre, each component allowing the execution of tasks and including a security management configuration associating a status message, forming a log, with the execution of a task of the component, each log associated with a task indicating an event and having a local level, the control centre allowing the collection of a set of logs to supervise the network, the method including: detecting a stimulus by a control centre; determining a component associated with the stimulus detected by the control centre; modifying the first level of verbosity of the component to a second level of verbosity during a first given period, the modification being launched by generating a supervision command by the control centre, the second level of verbosity being defined according to the stimulus.

摘要： A secure communication method between at least one first entity and at least one second entity with a communication link in at least one network, includes a step of encryption, by the first entity, using a symmetric encryption algorithm, of content using a first key specific to the first entity; a step of aggregation, in a message, of the encrypted content with at least one key generation parameter specific to the first entity; a step of sending, by the first entity, of the message to the second entity; a step of determination, by the second entity, of the first key specific to the first entity using the key generation parameter specific to the first entity, of a first secret known by the second entity and of a key generating function; a step of decryption, by the second entity, of the encrypted content of the message received, using the first key.

摘要： The method for reliabilisation of the supervision of a network comprises: acquisition of a set of events, said events comprising a time stamp corresponding with the emission time of said event; storage of the received events; storage of at least one scenario (SC) comprising a first sequence (S1) of events to be received within a time interval threshold (ΔTs) and a first condition (CD1) to be satisfied; detection of at least a part (pS2) of a received second sequence of events (S2) similar to the first sequence (Si); determination of a second emission time interval (ΔT3) of the second sequence (S2); verification that the first condition (CD1) of the scenario (SC) is satisfied in function of the determined emission time interval (ΔT3), the time interval threshold (ΔTs) of scenario (SC), and the first sequence (S1) and the second sequence (S2) received, and generation of a second status message (M2ET).
