Lightweight Two-Factor Authentication With S-Box Flipping Module for IoT Security

Abstract

In recent days, the usage of cloud computing in wireless networks offers more advantages to the users by storing resources with less complexity and ease to control. Data security is considered a critical aspect in a cloud computing environment due to the sensitive and confidential information of users stored in IOT. So, this paper introduces a Lightweight and Privacy-Preserving Two-Factor Authentication (TFA) with S-box based Flipping Module (SBFM) to provide data security for a user. The proposed scheme uses Unclonable Function Key (UFK) to provide a better solution for highly-secured cloud computing. Moreover, Reconfigurable Unpredictable Response Value (RURV) helps to generate the different response values for every clock cycle in IoT. Finally, Spartan 6 Field Programmable Gate Array (FPGA) performances of the proposed TFA-RURV-IoT are compared to existing TFA-URV-IoT protocols, whereas the simulation results show that proposed TFA-RURV-IoT achieves better results in terms of LUT, slices and flip flops.
