| Abstract | ||
| Advances in the design of keystream generator using swarm intelligence techniques are reported.In this paper particle swarm optimization algorithm for generating random keystream with large complexity is presented. Particle swarm technique is adapted to locate the requirements(larg period ,larg linear complexity, good randomness and high order of correlation immunity). The definitions for some cryptographic properties are generalized, providing a measure suitable for use fitness function in a particle swarm algorithm, seeking randomness that satisfy both correlation immunity and the large linear complexity. Results are presented demonstrating the effectiveness of the proposed method. | ||
