Practical Data Transmission Scheme for Wireless Sensor Networks in Heterogeneous IoT Environment

Wireless Sensor Networks (WSNs) are foundation of Internet of things (IoT). Sensors are mainly deployed for collecting data which will be transmitted to IoT servers. In trying to prevent unauthorized users from stealing, faking even destroying data, it is critical to design a secure data transmission scheme for WSNs in the IoT. In recent years, a great many data transmission schemes have been put forward successively, however, most of these schemes required the sender and the receiver to be in the same network domain, or to share the same system parameters in different environments. Moreover, almost all of data transmission schemes cannot achieve known session-specific temporary information security (KSSTIS). For solving these problems, we proposed a data transmission scheme for WSNs in heterogeneous IoT environment by using heterogeneous ring signcryption. The data transmission scheme allows WSN node under the circumstance of certificateless cryptography (CLC) to transmit the collected data to an IoT server under the public key infrastructure (PKI) environment with different cryptographic system parameters. The proposed scheme which proves to be safe under the Computational Diffie-Hellman (CDH) problem in the random oracle model. Also, the proposed data transmission scheme is practical for wireless sensor networks in heterogeneous IoT environment through the efficiency analysis.
