The invention relates to a method for managing the reputation level of a first communication device (100), said reputation level (103) being stored into a first secure enclave (102) embedded in said first communication device (100). The method comprises the steps of: receiving from the first communication device (100) by a second communication device (110) an information message; verifying that the information message is consistent with data obtained from a sensor embedded in the second communication device (110); generating a feedback message by the second communication device (110) to be transmitted to the first communication device (100) indicating if the information message is consistent for the secure enclave (102) of the first communication device (100) to update its reputation level.
