    摘要: A method implemented by a client transmitting entity included in a 3GPP MCS (3rd Generation Partnership Program Mission Critical Services) standard network, the client transmitting entity being configured to transmit a plurality of contents intended for at least one client receiving entity included in the network, the client transmitting entity and the client receiving entity being affiliated with a same communication group, the method including generating, by the client transmitting entity, a group user key identifier, the group user key identifier being specific to the communication group and being used to encrypt the content, the generation being repeated each time a predetermined event takes place.

    摘要: A method for configuring access by a user to fallback communication services, includes sending by an application client an authentication request to an identity management server; and in the event of rejection: the identity management server allocates a fallback identifier and sends the fallback identifier to the application client; the application client sends a request for fallback user profile to a configuration management server; the application client sends a request for fallback multimedia group profiles to a multimedia group management server; the application client sends a request for fallback multimedia group encryption keys and private communications encryption keys to an encryption keys management server; once the application client has received the fallback user profile, the fallback multimedia group profile(s), the fallback multimedia group encryption key(s) and the private communications encryption key(s), the user can access the fallback communication services.

    摘要: A system for the transmission of group multimedia data to a set of clients affiliated to a communication group, the communication system including a control entity; a signaling participating entity; a participating entity supporting a unicast distribution service, called unicast entity; a participating entity supporting a broadcast distribution service, called broadcast entity; the communication system including a software bus linking the different participating entities to convey information messages exchanged between the different participating entities, for: enabling each unicast entity to maintain a first list of multimedia clients for each communication group to which has become affiliated at least one multimedia client; maintain a second list of multimedia clients for each geographic zone; and enabling each broadcast entity to maintain a third list of multimedia clients for each communication group to which has become affiliated at least one multimedia client.

    摘要: The method for validating the status of a memory of a simulator of a cryptographic component able to save data generated by a cryptographic function, includes a step carried out in the simulator including a first execution of a first cryptographic function generating: a first status of the first memory, and a first result of the first command; a step carried out in a test bench including a second execution of a second simplified cryptographic function, with the first and the second functions carrying out the same operations generating: a second status of the memory, and a second result of the second command; a step of validating including comparisons: of the first status and of the second status and of the first result and of the second result.

    摘要: A method implemented by a client transmitting entity included in a network according to the 3GPP MCS standard, the client transmitting entity being configured to transmit content intended for a client receiving entity included in the network and being affiliated with a same communication group, the method including selecting a security context from among: a security context with endpoint diversity formed by: a long master key identifier formed by the GMK-ID and the DMK-ID, or a short master key identifier formed by the GMK-ID or a short master key identifier formed by the GUK-ID or no master key identifier. A security context without endpoint diversity formed by: a short master key identifier formed by the GMK-ID or no master key identifier.

    摘要: A communication network enabling a plurality of user devices to access communication services, the communication being a private communication or a communication within a multimedia group to which at least one user device of the plurality of user devices is affiliated, the communication network including at least one dedicated signalling group making it possible to announce to at least one user device of the plurality of user devices affiliated to the dedicated signalling group the availability of at least one service for the dedicated signalling group.
