Novel Light Weight Hardware Authentication Protocol for Resource Constrained IoT Based Devices

Recently, a great deal of physical equipment has been linked to the Internet of Things (IoT) by use of the Radio Frequency Identification (RFID) technology. Moreover, security is the primary concern for RFID-enabled IoT devices. In order to prevent security risks, mutual authentication is a vital step. The majority of authentication protocols are resource-intensive and computationally expensive to implement. Hence, a low power and lightweight hardware implementable security protocol is well suited for RFID enabled resource constrained IoT devices. This paper designed a novel light weight mutual authentication protocol using multifunction digital logic based encoder architecture for RFID based IoT systems. The proposed multifunction logic circuit generates different logical outputs for every random selection of control inputs, which improves security drastically. The protocol is narrated in Verilog Hardware descriptive language and realized in Altera DE2 Cyclone II (EP2C35F672C6) FPGA board and synthesized in 180 nm and 90 nm technology ASIC platform. Experimental results are compared with the state-of-the-art protocols, which demonstrate that the proposed protocol is much more suitable for lightweight applications. In addition, the security of the protocol is also formally verified using the standard BAN logic algorithm. Finally, the proposed protocol is real-time implemented and verified in Jennic JN5168 Test Bed using Contiki OS for resource-constrained IoT applications.
