Hash functions are employed in cryptography to ensure integrity and authentication within the blockchain. The widely used SHA256 algorithm has faced recent attacks, prompting the development of stronger hash fu
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...
SHA-2,名称来自于安全散列算法2(英语:Secure Hash Algorithm 2)的缩写,一种密码散列函数算法标准,由美国国家安全局研发,由美国国家标准与技术研究院(NIST)在2001年发布。属于SHA算法之一,是SHA-1的后继者。其下又可再分为六个不同的算法标准,包括了:SHA-224、SHA-256、SHA-384、SHA-512、SHA-512/224、SHA-5...
