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

The use of cryptography algorithms based on hardware to protect the security and privacy of the loT systems is in huge demand. However, hardware-based security systems are similar to software-based in that they can be attacked by a type of malicious code called malware. In this article, we used the self-applied cryptography algorithm on the hardware-based to protect the data security of loT systems, and that gives the trustee than using software-based of hardware-based inform of ASIC chip. Detailly, we have developed an SoC FPGA system including main factors are a built-in ARM processor core, a self-implemented IP core acting as 128-bit AES co-processors, and SDRAM memory. Furthermore, this system has been placed on the DE10-Standard board and ran with an application in Linux operations. Besides, we have applied the DMA technique to obtain high-speed data transfer. As a result, our cryptosystem is compact and can achieve high performance with low frequencies. Details, the DMA Controller and 128-bit AES IP core operate at a frequency of 150 MHz, and they can reach the speed of 1200 Mbps and above 700 Mbps, respectively.
