Riassunto analitico
During the last ten years, the presence of sensors in common life has become pervasive. Sensor nodes are used in many areas of interest: from military fields to environment monitoring, from medical applications then to domotic uses. One of the most common radio communication protocol designed for Personal Area Network (PAN) is described by the IEEE 802.15.4 standard.<br><br>Data communication among devices can be protected on a per frame basis, allowing to provide data authenticity and data con dentiality.<br><br>With reference to the IEEE 802.15.4 MAC layer, the security sublayer was implemented, providing the main security features the standard describes. In particular, the TinyOS implementation for the TelosB mote was considered, as well as its CC2420 chipset features.<br><br>The main goal of this work is exploit the IEEE 802.15.4 security mechanisms for both sending and receiving ciphered frames, as well as integrate IEEE 802.15.4 security suite with the security features provided by the CC2420 chipset.<br><br>A two nodes network scenario was considered. Besides, ciphering mode only was used, while all security options and parameters were statically set up.<br><br>Finally, a simple application was developed, in order to test and evaluate the network activity.
