TRUST-BASED DATA PROTECTION AND AUTHENTICATION TECHNIQUE FOR IOT-SENSOR NETWORKS

In IoT environments, sensor nodes often need to transfer a massive quantity of identified data to the doorway in a petite duration.
Therefore the door needs to usually validate the collaborating strategies in every period. But traditional security methods which involve
cryptographic operations and privacy protections are not applicable in IoT networks, due to their resource constraints. Hence we
propose to design trust-based data protection and authentication technique for IoT-WSN. In this technique, the behavioral trust and data
trust values of each device are estimated by the data aggregator. Then, a total trust value is derived for each device using both types of
these trust values. During data aggregation, the aggregator omits the data from the tools, whose trust values are low. To protect the data
and perform authentication, a ticket-based message authentication code (MAC) is applied by the IoT sender. Simulation results show that
the proposed technique involves a higher delivery ratio with reduced energy consumption.
