| Abstract: | Aiming at the current faults of algorithm for video encryption which existed in security,compatibility and practicality,it was proposed a chaos based algorithm for video encryption.In addition,this algorithm was based on stream-encryption algorithm,and adopted the mathod of direct-encryption algorithm,in order to be used on different video coding standards and be easily carried out using hardware.According to theoretical analysis and results of experiments,it was proved that this algorithm had execllent security and tiny dalay. |
| Keywords: | streaming media stream-encryption chaos algorithm |
