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