Light-Weight Secure Aggregated Data Sharing in IoT-Enabled Wireless Sensor Networks

Internet of Things (IoT) is a network physical objects or things that can communicate and share information. In IoT-enabled Wireless Medical Sensor Network (WMSN), the smart sensing devices remote patient monitoring data towards central repositories. During medical aggregation transmission, security mandatory to guard against intruders. The main problem in existing base schemes complex multiplication operations are used for batch key creation. These computationally expensive require huge memory space at aggregator node (AN). This paper presents lightweight Secure Aggregation Transmission Scheme (SATS) secure computation transmission. SATS provides XOR operation obtaining keys instead operation. Furthermore, AN Receiving Message Algorithm (ARMA) presented aggregate generated by sensor nodes. Extractor (RME) algorithm decrypt message perform verification Fog-Server. protects several threats such as denial service attacks, man middle attack, reply attacks. proposed simulated using simulation tool NS 2.35. results show transmission reducing communication costs.The cost scheme 14%, 23% 59% AN, Fog-Node 6.5%, 21.5% 51%, Communication 6%, 3%, 4% Node, 9%, 12% better than PPDAS, IDAP, ASAS respectively. compared with relevant it storage capacity, computations cost, communications energy consumption.
