User Authentication Scheme for Internet of Things Using Near-Field Communication

In the Internet of things (IoT), the user authentication process is becoming more critical with the growing number of the services provided by IoT. Securing access to these services by the user authentication process leads to high security to prevent any attack on the IoT network. The approach keeps the private information secured efficiently and ensuring that only authorized users can access this information. The proposed scheme uses only Chaskey hash function and XOR operation. The security analysis proves that it is immune to different types of attacks. Furthermore, the scheme is faster, lighter on resources and energy consumption compared to other existing schemes. Finally, we compare the proposed scheme to several other existing schemes on several aspects highlighting main differences.
