Linear and Differential Cryptanalysis of SHA-256

Linear and Differential Cryptanalysis of SHA-256
The one-way hash function plays an important role in digital signatures and message authentication from the viewpoint of security. No effective attacking method has been discovered to the algorithm of hash function standard. In this study, we tried to attack SHA-256 in encryption mode using linear and differential cryptanalysis to solve a private key ...
