Secure data transmission is a critical issue for Wireless Sensor Networks (WSNs). Clustering is an effective and practical way to enhance the system performance of WSNs. Proposed a CRP for secure data transmission for Cluster-based WSNs (CWSNs), where the clusters are formed dynamically and periodically. CRP uses Digital SIgnature (DSI) scheme and the identity-based Online/Offline Digital Signature (DSOO) scheme, for security. In DSI security relies on the hardness of the Diffie-Hellman problem in the pairing domain so that it uses the hashing technique for signing and verification.
