  • Patent number: 11394723
    Abstract: Methods for validating delivery of content and verifying a delegation of delivery of a content, and corresponding devices and computer program products. A method is proposed for validating a delivery of a content to a client terminal. Such a method includes receiving, by the client terminal, an address, referred to as the received address, in response to a request sent to an address server in order to obtain an address of a delivery server of the content. The request includes a piece of information relating to the delivery server. Such a method further includes receiving, by the client terminal, a piece of information relating to an authentic address associated with the delivery server, the information being sent by a server of the content supplier, and determining the validity of the received address with respect to the authentic address on the basis of the information relating to the authentic address.

  • Publication number: 20220159037
    Abstract: A method for securing the transmission of at least one data packet along a data path of a telecommunications network is disclosed. According to such a method, a security device performs: obtaining a variance delay representative of a difference between an actual end-to-end transit delay of the at least one data packet along the data path and an expected end-to-end transit delay of the at least one data packet along the data path; and securing the transmission by implementing at least one security action based on the variance delay.

  • Patent number: 11258770
    Abstract: A method for requesting proof of delegation for delivery of content to a client terminal via an encrypted connection. The content is referenced on a content server, to which the client terminal emitted a request to obtain the content. The content server has delegated the delivery of the content to a primary delivery server. The method is implemented by a secondary delivery server, to which the primary delivery server has delegated the delivery of the content. The method includes: receiving a request to establish an encrypted connection, from the client terminal, including an identifier of the content server; emitting a request for proof of delegation of delivery, addressed to the content server; receiving of a message from the content server, including an encryption key; emitting a response for establishing an encrypted connection, addressed to the client terminal; and establishing the encrypted connection with the client terminal using the encryption key.

  • Publication number: 20220030468
    Abstract: A method for allocating at least one transmission resource from among a plurality of resources, intended for routing a first item of data relating to a first application in a communication infrastructure. The method is implemented in a distributed management entity for managing the plurality of resources and includes: receiving, from a centralized management entity, an allocation message for allocating a plurality of resources having a set of transmission features for a second item of data relating to a second application; and assigning at least one resource of the plurality to the transmission of the first item of data. The method furthermore includes selecting a feature of the set for the transmission of the second item of data on the resources of the plurality that are not assigned to the transmission of the first item of data.

  • Patent number: 11231969
    Abstract: A method of auditing at least one virtualized resource deployed in a cloud computing network, implemented by an administration device in respect of the at least one resource, able to administer virtual network functions, the virtual infrastructure or the network services. The method includes: storing a set of rules of the audit which are associated with the at least one virtualized resource; receiving from the at least one virtualized resource a message including an item of information about an event arising on the virtualized resource; correlating the item of information received with the set of stored rules; and if the correlation is positive, sending, to a recording device, a command message for writing at least one datum linked to the item of information received in a data register associated with the at least one virtualized resource.

  • Publication number: 20220014972
    Abstract: A method for preserving a transmission rate of second data transmitted by a first terminal destined for a second terminal attached to at least one access device in a communications network. A communications network node capable of routing the second data identifies an inability of the at least one access device to send first data received from the first terminal to the second terminal, processes the first data received from the first terminal during the identified period of inability of the at least one access device, and transmits to the first terminal a notification indicating that the first stored data is not subject to congestion.

  • Publication number: 20210399965
    Abstract: A method is proposed for monitoring a connection between end devices via a communications network. A set of modes having at least two monitoring modes and a ranking order associated with the set of modes, are agreed upon between the end devices and a network device present on a path between the end devices. The method includes an activation of the set of modes, corresponding to an activation of the first mode according to the ranking order; then an activation, according to the ranking order, of each other mode of the set of modes. Each monitoring mode includes at least one mechanism implemented by at least one of the end devices and enabling the network device to perform at least one function of monitoring the connection.

  • Publication number: 20210273926
    Abstract: The communications established on a communication path between two nodes, for example between a client and server, are increasingly encrypted, at least from the transport layer and to the application layer in the Open Systems Interconnection model. However, the devices present on the communication path may in certain cases or for certain services, intervene not only to transport the messages but also to read, edit or add data in the message. In addition, it may also be desirable that only “authorized” devices can carry out these actions. In order to intervene on these data, it would be necessary that the devices on the communication path have available all the keys used by the nodes to encrypt and decrypt the data of the messages, which is difficult to envisage.

  • Publication number: 20210273882
    Abstract: A method allowing execution of transmission functions hosted in intermediate pieces of equipment of a path established between two pieces of communication equipment. End-to-end encryption systems are designed to resist any surveillance or tampering attempt, as no third party can decrypt or modify the communicated data. There is a solution which, depending on the connection opening requests of the applications, allows to select and assemble the transport protocols necessary for the operation of the application. However, this method is local: this protocol stack is only assembled at the pieces of communication equipment constituting the ends of the connections. Consequently, the requests emitted by these applications are not transmitted to the intermediate pieces of equipment which host the desired functions.

  • Patent number: 10979750
    Abstract: Checking a certificate of delegation, from a first server to a second server, for delivery of content referenced on the first server, and addressed to a client terminal. The terminal: emits a first message requesting the content, addressed to the first server, via a first encrypted connection; receives a redirection message from the first server, including an identifier of a third-party server; obtains an address from the second server, based on the identifier received in the redirection message; emits a request to establish a second encrypted connection between the terminal and the second server, including an identifier of the first server; receiving a certificate of delegation signed by the first server from the second server, via the second encrypted connection; verifies the certificate by an encryption key of the first server; and if valid, emits a second message requesting content, addressed to the second server, via the second encrypted connection.
