H.264-based Multiple Security Levels Net Video Encryption Scheme
Yan Li, Main Cai · 2009
Due to traditional and single video encryption algorithms canpsilat meet the needs of various net multimedia services. This paper references the H.264 video coding standard and video encryption algorithms, analyzes the existing video encryption algorithms from security, speed, compression ratio and date operability, and classes the video encryption algorithms according to security. It also proposes the multiple security levels net video encryption scheme. The scheme could meet requirements of different net videos, provide safe and real-time services, improve the utilization of net resources, and have a good adaptation to network.
