Abstract

Provides is a method (100) for determining, onboard a first mobile entity (10), a level of trust (14) for a second mobile entity (20) in communication with the first mobile entity (10), and a communication system (200) implementing the method (100). The method (100) comprises determining (101), by the first mobile entity (10), direct trust data (11), calculating (103) an initial reputation indicator based on the direct trust data (11), including a belief value, a disbelief value, an uncertainty value, and a base trust rate, calculating (104) a confidence level (12) based on the belief value, the base trust rate, and the uncertainty value, and determining (107) an updated reputation indicator (13) based on the initial reputation indicator and the confidence level (12). The base trust rate is indicative of the trust level for data transmitted from an unknown mobile entity that has not been in contact with the first mobile entity (10) in the past. Each of the positive interactions and negative interactions corresponds to an interaction where the data received from the second mobile entity (20) match or do not match defined quality criteria, respectively. The updated reputation indicator (13) indicates a level of trust (14) of the first mobile entity (10) in the second mobile entity (20).
