An efficient scheme for anonymous communication in IoT

Security and privacy are challenging task in resource constrained in Internet of things (IoT) and Wireless Sensor Networks (WSN). Hence, anonymity and trust are prominent for many common IoT and WSN applications, in which we conceal nodes identity and give confidential data to a trusted node. The majority of exiting IoT security solutions cannot achieve complete security needs and/or have large computation overheads. In this paper we design a secure generic model for IoT and WSN to ensure anonymity, data secrecy and trust between nodes. Our work is based on lightweight key agreement protocol, the Identity Based Encryption (IBE) and Pseudonym Based Encryption (PBC).
