Over the past years, the deployment of sensor networks into industrial environments attracted a lot of several business domains. Therefore, an increasing number of applications are developed in several business domains, ranging from defence, public security, energy management and traffic control to health care. Sensor networks are particularly interesting due to their ability to control and monitor physical environments. Nevertheless, several technical (e.g. remote management, deployment) and security (e.g. user's privacy, data confidentiality and reliability) challenges deter that integration. The present proposal aims at supporting and securing the integration of sensor networks into large scale industrial environments.In the scope of TWIST, we will identify number of use cases, from nuclear plant facility to supply and demand energy management, which illustrate the integration of sensor networks into industrial environments. From those use cases, user's privacy, node authentication or data reliability appear as the most important security requirements.The TWIST project will provide a platform enabling business application to command and control sensor network in a secure and trusted way. Integrating commercial off-the-shelf or pre-standard devices, that platform will serve as a mediation layer between the sensor network and industrial applications. Empowered with security architecture addressing the major business application security requirements (e.g. user's privacy, data confidentiality, reliability), that platform will be validated based on the identified use cases. Finally, the scientific and technical outcome of TWIST will be its contribution to standards, such as IETF 6lowpan. These standards will be enhanced to make them capable of addressing the use cases proposed by the project.
