A secure light weight authentication protocol for wireless sensor network in internet of things

With the advancement of cloud and Internet of Things (IoT) technology, mobile phones, RFID systems and wireless sensor networks can be integrated to form heterogeneous systems to execute smarter applications. However, data exchange between remote cloud and sensor node via internet poses critical security challenges. The major challenge is the authentication and key exchange among the communication agents. In addition, resource constrained devices such as RFID tags, sensors in WSN and IoT integration (WSNIT) would require robust and light weight authentication schemes. To combat these issues, we establish in this paper a first of its kind of a WSN security protocol in IoT, which is light weight and resistant to cryptographic attacks.
