Public Protection and Disaster Relief (PPDR) communications are currently at the edge of a considerable technological evolution, which will create significant opportunities for novel products, novel services and novel functionalities. These networks are used by public protection entities and rely on mature technologies such as TETRA and TETRAPOL. Despite their maturity they were not designed for transmitting large volumes of data, images or live video – invaluable functionalities in the scope of public protection and disaster relief. The progress in Long Term Evolution (LTE) technology includes functionalities that enable LTE to replace TETRA and TETRAPOL technologies for PPDR communications.

The objectives of Project Mobitrust are to research and develop a security management platform for this new generation of PPDR terminals based on LTE, including several aspects: adequate security mechanisms for PPDR scenarios, trusted execution environments; support for forensic analysis fully integrated with the PPDR infrastructure; remote management of applications and terminal security; reinforcement of situational awareness (using data collected from biosensors, environmental sensors and other peripherals associated with the PPDR terminals); and controlled use of BYOD (Bring Your Own Device) paradigms in disaster relief scenarios.
