A Reliable Approach to Secure IoT Systems using Cryptosystems Based on SoC FPGA Platforms

Cryptography is associated with the process of converting ordinary plain text into ambiguous text and vice versa. Hardware Security plays a major role in most of the applications which include net banking, e-commerce, military, satellite, wireless communications, electronic gadgets, digital image processing, etc. in this paper presents AES prototype system that secures the IoT system by hardware-based security system. Specifically, AES 128-bit symmetric cryptography algorithm is implemented for SoC level FPGA to avoid malware in software and hardware. This work also describes the optimal architecture for AES with improved security system. This proposed system offers different operational models of AES systems that can be applied in practice. Experimental results prove the system’s throughput, maximum operating frequency, and hardware utilization resources of proposed AES over conventional models.
