Abstract: The hash algorithm BLAKE is one of the five candidates for SHA-3(Sccurc Hash Algorithm-3) competition at the last round. This paper described the design and implementation of BLAKE based on Matlab. Our program with a GUI(Graphic Uscr Interface) can be used both in practical Balke Hash value calculation and Blake teaching or experi- ments.
