SummaryTrust management is an emerging security approach used to conduct nodes' relationships in mobile ad hoc networks. It relates to assigning a trust level to each network component based on its cooperative behavior with respect to system goals. Because of its infrastructure‐less nature, frequent network dynamics, and severe resource constraints, it is complex to establish trust in such a network. Mainly, trust systems are vulnerable to attacks that make use of inherent properties of the trust model to alter the accuracy of estimated trust levels, referred to as trust‐distortion attacks. Because of the contradictory nature of such attacks, their detection can be confusing, complex, and energy‐demanding, especially in multiattack environments. To handle such threats, we propose a Green Trust‐distortion Resistant Trust Management Scheme, called GTRTMS, which handles different trust‐distortion attacks in multiattack environments. The proposed solution self‐adapts its trust knowledge monitoring according to the network context to conserve the energy of mobile nodes and reduce the produced CO2emissions. Simulation results prove that GTRTMS exhibits significantly better performance than the other counterpart in presence of simultaneous and contradictory different trust‐distortion attacks.
