A SUGGESTED SUPER SALSA STREAM CIPHER

Abstract

Salsa (20) cipher is speedier than AES cipher and itsoffered superior security. Salsa (8) and Salsa (12) are specifiedfor apps wherever the grade of security is less necessary thanspeed. 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 differentialattacks. Furthermore, in each iteration, the diffusion ofgenerated keystream will increase due the effect of changing thevolume acting for one element of the array is not fixed. Thegenerated keys of the suggested Super SALSA keystream aredepicted as simple operations and a high hardiness randomlykeystream by exceeding the five benchmark tests. Likewise, it'spresenting a situation of equilibrium between complexity andspeed for Salsa (8, 12 and 20).
