Problems solved by technology

Therefore end-to-end security cannot be guaranteed
This type of security for extended sensor networks will be more limited due to the use of several consecutive networks

Embodiment Construction

[0073] definition

[0074] The present invention relates to communication security and authentication between two communicating entities.

[0075] The description refers specifically to two entities, a client and a server. The client C1 is for example the connected object, and the server S1 is of the data server type, with which they receive the payload data Data1 collected by the connected object's sensors.

[0076] In this description, a first communicating entity C1 designates a communicating entity C1 that transmits, for example, payload data collected by one or more sensors. Sensors measure physical quantities such as temperature, pressure, vibration, force and acceleration. The first entity may include one or more actuators. The first entity may also comprise a set of sensors and actuators, the sensors providing eg information about the status or position of the actuators.

[0077] The second communicating entity S1 designates the communicating entity S1 receiving ...

Abstract

The invention relates to a method for communication between at least two communicating entities (C1, S1), a first communicating entity (C1) generating at least one data message comprising a payload (Datai) and an authentication heading (Tokeni), the method being characterised in that it comprises: generating a context parameter (ContextP1) comprising at least one datum representing the material configuration (CtrIProg) of the first entity (C1); generating a security profile (PRO_SEC) in the authentication heading (Token1), which defines the conditions of encoding the payload (Datai) of the message and of generating a signature (Sign1) by an algorithm (Signing_Module1) applied at least to the payload (Datai) of the message; including the signature (Sign1) in the generated message; insertinga stored identifier (C1_ld) of the first communiccation entity (C1) into the authentication heading (Token1); and inserting the safety profile (PRO_SEC) into the payload or into the authentication heading.

Description

technical field [0001] The field of the invention relates to securing communications between two communicating entities, such as one or more entities managing sensors or driving actuators, and a central entity remotely managing hardware resources and communicating via a network interface. [0002] In particular, the invention relates to secure communications that do not require state management. The field of the invention also relates to safety and securing data in the generation of control data as well as in the driving of actuators, in particular by establishing a dedicated secure communication that provides flexibility by taking into account limited computing resources architecture and is applicable to the Internet of Things. Background technique [0003] The Internet of Things and highly digitalized environments emerge with, for example, the establishment of information flows for management, backup or interaction purposes. Therefore, methods of securing communications ...
