of a hazard area or when actors pass from one room to another. To protect actors’
privacy, it is required to transmit data captured by the sensors to the base station on
a secure channel providing data confidentiality.
e ACUBE implementation rely on TeenyLIME and TinyKey but, differently

final integration with the project-specific application, although packet rate (one
packet sent every 3 s), packet routing (single hop), packet size (100 bytes), and
LPL sleep interval (50 ms) was compliant to the project specifications. A
