نویسندگان
چکیده
The Internet of things (IoT) has become a significant element of next generation. IoT is a proposed development of the internet in which the objects have network connectivity able to transmit and receive data. The IoT applications such as smart homes, smart cities and health care. WSN is an important technology of IoT. Typically sensor nodes are considered resource constrained device with limited battery power and computation capabilities. Hence group communication is efficient than device to device communication. Security is responsible for transmitting information without hacking. Security is used to provide guarantee for integrity and authenticity of the message transaction. Secure group key establishment is used to provide effective message delivery between resource constrained sensor nodes. In this proposed method two protocols are designed for secure group communication. These two protocols are based on ECC operation and used to avoid Man In The Middle (MIIT) attack. Each protocol are defined in term exact IoT application development and examined based on its security, performance, throughput and scalability. Network coding method is used to increase the performance, throughput, as well as resilience to attacks and eavesdropping. According to the performance evaluation results, the security analysis supports the stronger security features of those protocols compared to reference solutions. The addition of a digital signature gives resistance against MITM attacks. This will provide the stronger security features in the multicast communication. Keywords—Wireless sensor network, Internet Of Things, Group communication, Security, Group key Establishment. _________________________________________________________________________________________________________________
