SYSTEM AND METHOD FOR SECURING MACHINE-TO-MACHINE COMMUNICATIONS

This invention concerns the implementation of end-to-end security for the communication between objects in the domain of the Internet of Things (or Internet of Objects). The purpose of the patent is dealing with the setup of secure authorized information channel between data source (M2M device) and data consumers (consumer entity). According to the present invention, the access to a M2M device by a consumer entity (consumer application) is controlled by a M2M authorization server. The M2M authorization server is the entity in charge of managing access rights for the M2M device and makes the decision regarding the access to the resource by the consumer entity (consumer application). The M2M server is an entity that enforces the decision and enables the access to the M2M device. When a consumer application needs to communicate with a M2M device, the present invention proposes a method for authorizing a consumer application to access a M2M device and for encrypting the communication between the consumer application and the M2M device. The M2M authorization server computes security credentials which are sent to the consumer application.
