Cryptanalysis of Protocol for Heterogeneous Wireless Sensor Networks for the Internet of Things Environment

Access and connectivity to everything on the Internet of Things are closely tied to the wireless sensor network environment. In an IoT environment, a user can access a desired single sensor node without first connecting to the gateway node. Chen et al. proposed an efficient and safe protocol in this environment. Unfortunately, their plans have security weakness. We describe the protocol proposed by Chen et al. and describe two attack techniques for that protocol. The first is that it is vulnerable to password guessing attacks. Also, their protocols cannot defend against session key attacks. Finally, this paper proves that the target protocol is unsafe.
