  • Method and device for establishing session keys
    Patent number: 9787651
    Abstract: A method and a device for setting up a session key between a source entity and a target entity in a communication network comprises a plurality of communicating entities. The method, which relies on the use of symmetrical cryptographic primitives, provides each entity in the session with protection against denial of service attacks by setting up a session in four or five message exchanges.
    Type: Grant

  • Method and device for forming a secure wireless network with limited resources
    Patent number: 9774585
    Abstract: A method and a device for forming a secure wireless network for nodes with limited resources, between which no previous trust relationship exists is provided. The method can be used to generate a list of neighboring nodes for a requesting node and subsequently establish a secure channel between the requesting node and an authentication entity. A security association is established with each neighboring node on the basis of a master session key received via the secure channel.

  • METHOD AND SYSTEM FOR AUTHENTICATING THE NODES OF A NETWORK
    Publication number: 20150149767
    Abstract: A system and a method are provided for authenticating the nodes of a communication network in order to access the services of a service provider, and includes a collective authentication of the nodes, performed in a single exchange between the nodes of the network declared in a group and an authentication server. Depending on the result of the authentication, the service provider is provided with cryptographic material in order to implement individualized controlled access to the resources or to the services offered for each node.
