Scrambling method based on itinerary of tent map
Leyi Zhuang · Journal of Computer Applications · 2009
An audio and image scrambling method based on the itinerary of tent map was proposed.The codes generated by the itinerary of tent map could be applied in audio signal scrambling.In addition,digital image could also be scrambled as the map was extended to the 2-D case.The scrambling degree,period and robustness were discussed as well.Generally speaking,the proposed method owns larger period and better scrambling degree compared with the traditional scrambling by Arnold transformation.
