Secure group communication transfers message from one member to another confidentially. Key management for secure communication in wireless networks is primitive based on cryptographic techniques. Intercluster routing was used to improve wireless networks security. In the new scheme, Minimum Spanning Tree (MST) and GBest-BAT algorithm are computed to identify Cluster Heads (CH) with a concept of backup nodes being introduced for effective key management. This study proposes MST formation for inter-cluster routing and it is optimized with GBEST- BAT algorithm.
