Malicious behaviour detection in Wireless Sensor Networks (WSNs) is essential because of the increasing number of security threats and the resource-constrained nature of these networks. Standard detection systems often face limitations such as poor scalability, limited accuracy, and inability to adapt to varying data distributions across clients. To address these issues, the proposed method is developed to improve performance and data security. Initially, the Dilated Stacked Convolutional Cross-Attention based Bidirectional Gated Recurrent Unit (DSC2-Bi-GRU) technique is used to detect malicious behaviour in WSNs by integrating Dilated Stacked Convolution (DSC), cross-attention, and Bidirectional Gated Recurrent Unit (Bi-GRU). Federated Learning (FL) is used for decentralized training among dispersed sensor nodes (SNs), enhancing data integrity and reducing risks of centralized data breaches. SNs collaborate to update a global model without exchanging raw data, dramatically boosting privacy and scalability. It is enhanced by using Differential Privacy Stochastic Gradient (DpSG) and Adaptive Elliptic Curve Cryptography (AECC) to ensure privacy and secure communication. Here, DpSG is used to include noise during the aggregation process to ensure privacy. Then, the AECC is used to secure the data by encryption. This proposed model captures spatio-temporal features, which enables accurate detection of intrusion while preserving data confidentiality, scalability, and resilience in resource-constrained and adversarial WSN environments. It is analyzed with other existing techniques to determine its superiority. The proposed approach achieved 0.9989% accuracy, 0.9986% precision, 0.9983% Recall, and 0.9949% F1-score.
