SHA-256hardwareThis work proposes an implementation of the SHA-256, the most common blockchain hash algorithm, on a field-programmable gate array (FPGA) to improve processing capacity and power saving in Interne
Section 2 presents previous work on imple- menting SHA-256 on FPGA solutions. Section 3 is divided into three subsections that introduce the background of the blockchain (Section 3.1), the IoT in a blockchain context (Section 3.2), and a subsection on the SHA-256 algorithm (Section 4),...
This work proposes an implementation of the SHA-256, the most common blockchain hash algorithm, on a field-programmable gate array (FPGA) to improve processing capacity and power saving in Internet of Things (IoT) devices to solve security and privacy issues. This implementation presents a differ...
