Present system relates to a method for authenticating a first device, the method being executed by a second device, the second device comprising a database, the database storing a profile associated to a user of the first device, the second device using the profile of the user to generate a first challenge comprising a question and a corresponding response for authentication of the first device, the method comprising, upon successful authentication of the first device using the first challenge, the steps of collecting contextual information from the first device and updating the profile associated to the user of the first device with the received contextual information for a subsequent generation of a second challenge for authentication of the first device.

Method for authenticating a device

The invention relates to a method for securing a request for executing a first application (P) in a first device () of a secured environment, by a second application (P) located in a second device (), said method including the following steps: receiving a first request to execute the first application, from the second application; generating a random number and a session key that is dependent on the random number, sending said random number to a trusted entity (), said random number being intended for enabling the trusted entity to generate the session key, receiving a second request for executing the first application, from a third application (P) generated by the trusted entity and transmitted to the second device, said third application including the session key, authenticating the third application by means of the session key, said authentication being the condition for the execution of the first application.

Method for securing a request for executing a first application, by a second application

The method allows communications means to be listed, for end-to-end broadcasting of information other than that required for managing multimedia sessions. After a selection () of communications channels through an infrastructure for managing multimedia sessions, the method provides via the application level, the establishment of a communication specifically using the selected communications channel(s). Purely descriptive/explanatory fields of characteristics of a session may be selected at an application level and used for conveying additional information in addition to the signaling protocol. It is thus possible to change the conditions for consuming/using the multimedia contents or the established flux. Instantaneity of the services and service use conditions may be obtained by requesting for example renegotiation in real time of a service when the conditions of use are modified (iconification of a TV/Video streaming flux in order to reduce the bandwidth used).

Method and system for controlling the establishment of communications channels for allowing transmission of multimedia information

To secure the execution of an application on an intelligent mobile telephone, each application is identified by an identifier and a table or rights is associated with each resource on the mobile telephone. Through a table of rights, access rights to the resource can be associated with an application identifier. This makes it possible to manage, for each resource, the applications that are allowed to invoke the resource. Moreover, the rights associated with a resource can only be modified by the owner of the resource.
