Salsa (20) cipher is speedier than AES cipher and its offered superior security. Salsa (8) and Salsa (12) are specifiedfor apps wherever the grade of security is less necessary than speed. The concept of this research is to suggest super salsakeystream utilizing various volumes matrices size (array (4, 4), array (4, 8), array (4, 16)) are used to increase the complexity ofkey stream and make it more reluctant to linear and differential attacks. Furthermore, in each iteration, the diffusion ofgenerated keystream will increase due the effect of changing the volume acting for one element of the array is not fixed. Thegenerated keys of the suggested Super SALSA keystream are depicted as simple operations and a high hardiness randomlykeystream by exceeding the five benchmark tests. Likewise, it's presenting a situation of equilibrium between complexity andspeed for Salsa (8, 12 and 20).
