  • In this project, CEA-Leti provides cybersecurity functions for the IoT devices and gateways and provides the Sensinact middleware to enable secured applications to be developed on top of the secured devices. These assets are integrated into the different use cases and are interfaced with the other partners’ assets.

  • Device and gateway security is ensured with project partner TST, which provides IoT sensors with WAN connectivity. These sensors have no on-board security and are must be combined with secure components, on which secured functions are performed. Key challenges reside in the efficiency of the solution and robustness to the security scheme. The secure component ensures the integrity of the IoT node with respect to firmware and software and is also used to authenticate the device for its network. Finally, it stores any sensitive information for communication encryption to the M-Sec cloud.

  • Gateway and cloud applications are secured on the software level with accountability and rights management on a per-resource basis in the Sensinact middleware. This enforces the privacy and confidentiality across applications and services in smart city use cases in which trust is an interoperability enabler. Sensinact’s studio is used for developing secured applications in a friendly way and makes smart applications auditable. Finally, Sensinact’s middleware will be the interface for the blockchain-based marketplace.

  • Objectives are to reach a level of trust for a full secured stack spanning from devices to a marketplace developed by partners based on blockchain technology.


  • Internet of Things (IoT) systems today tend to be built around the concept of IoT/cloud convergence, integrating heterogeneous data streams within cloud infrastructures and thus benefitting from the scalability, performance and capacity of the cloud. This approach is very efficient for certain IoT applications such as those applicable to big data processing. However, these architectures promote a centralized data collection and processing approach, which introduces several limitations in terms of the supported applications and business models they enable.
    The main goal of M-Sec project is to empower IoT stakeholders to develop, deploy and operate novel IoT applications based on a scalable highly decentralized paradigm, which facilitates incentivized peer-to-peer interactions between objects and people. Based on a defined social context, the project explores semantically interoperable interactions between people and objects
    beyond simple peer-to-peer information exchange and internetworking. Overall, the M-Sec paradigm will enable introduction and implementation of specific classes of applications and services that are not efficiently supported by state-of-the-art architectures. The M-Sec project will deliver a set of main concrete, added value results:
    • M-Sec distributed, self-organized, robust and trusted IoT infrastructure that empowers IoT stakeholders to develop, deploy and operate novel multipurpose IoT applications for smart cities on top of smart objects
    • An open IoT market of applications, data and services that provides the framework upon which objects and people can exchange value and defines the motivation incentives for humans and smart objects to interact
    • A sustainable ecosystem of stakeholders, roles, tools and infrastructures upon which new entrants and other players can build and experiment with the future application services
    • A parameterized model enabling further replication of the M-Sec approach and guaranteed return on investment and benefits.


  • The impact of the M-Sec project is its development of a secured, trustworthy IoT and Big Data framework for smart cities. This framework provides integrated security and privacy technologies to ensure full compliance with regulations applicable in Europe and Japan such as privacy regulations (GDPR, PIPA), data portability and free flow. The framework is expected to be a candidate for standardization.
