Researchers have introduced a new framework for enhancing the robustness of Graph Neural Networks (GNNs) specifically for directed graphs. This work addresses the limitations of existing methods by proposing a more realistic attack setting and a plug-in message-passing framework that strengthens GNNs without creating a false sense of security. The findings indicate that by leveraging the trust signals inherent in directed graph structures, GNN robustness can be significantly improved, leading to state-of-the-art performance in both clean accuracy and robustness against various attacks.
