En 中文

• We propose a dynamic robust trust evaluation model. • We explicitly map indirect trust relationships into direct connections. • We construct a multimodal spatial feature extraction and spatiotemporal fusion mechanism. • The model exhibits resilience against both trust-related attacks and global attacks.
