Abstract Wireless Sensor Network (WSN) is operated as a medium to connect the physical and information network of the Internet-of-Things (IoT) for exchanging information. Energy and trust are two key factors that assist reliable communication over the WSN-IoT. Secure data transmission is considered a challenging task during the multipath routing over the WSN-IoT. To address the aforementioned issue, secure routing is developed over the WSN-IoT. In this paper, the Multiobjective Trust based Crow Search Algorithm (MTCSA) is developed to identify the Secure Cluster Heads (SCHs) and secure path over the network. Further, data security while broadcasting the data packets is enhanced by developing the Hybrid Encryption Algorithm (HEA). This HEA is the combination of Advanced Encryption Standard (AES) and Hill Cipher Algorithm (HCA). Therefore, the developed MTCSA-HEA avoids malicious nodes during the communication which helps to improve data delivery and energy consumption. The performance of MTCSA-HEA method is analyzed using Packet Delivery Ratio (PDR), Packet Loss Ratio (PLR), energy consumption, End to End Delay (EED) and throughput. The existing methods namely Optimal Privacy-Multihop Dynamic Clustering Routing Protocol (OP-MDCRP) and Secure and Energy-aware Heuristic-based Routing (SEHR) are used to evaluate the MTCSA-HEA performances. The PDR of MTCSA-HEA for 100 nodes is 99.7449%, which is high when compared to the OP-MDCRP and SEHR.
