Data transmitted encryption for clustering protocol in heterogeneous wireless sensor networks

In this paper, elliptic curves Diffie Hellman-Rivest Shamir Adleman algorithm (ECDH-RSA) is a novel encryption method was proposed, which based on ECDH and RSA to secure transmitted data in heterogeneous wireless sensor networks (HWSNs). The proposed built under cheesboard clustering routing (CCRM). CCRM used regulate energy consumption of the nodes. To achieve good scalability performance by using limited powerful max-end sensors besides large min-end sensors. for sharing public private keys because its ability provide small key size high protection. authentication generated merging it with reference number node, distance cluster head (CH). Decreasing intake CHs, allows CH compile tha encrypted no need decrypt it. results simulation show that approach could maximize life network nearly (47%, 35.7%) compare low-energy adaptive hierarchy (Sec-LEACH SL-LEACH) approches respectively.
