摘要：

Recently, a fast and secure hash function SFHA-256 has been proposed and claimed as more secure and as having a better performance than the SHA-256. In this paper an improved version of SFHA-256 is proposed and analyzed using two parameters, namely the avalanche effect and uniform deviation. The experimental results and further analysis ensures the performance of the newly proposed and improved SFHA-256. From the analysis it can be concluded that the newly proposed algorithm is more secure, efficient, and practical.
