Description: 探讨了基于zigzag置乱的MPEG4视频数据加密技术，指出了这种方案在安全性方面的不足，提出了改进方
案。改进的方案中AC系数用不同的置乱表置乱，DC系数用高强度的加密算法AES加密。最后给出了改进后的加密效
果，并且从加密速度，安全性和码流变化三个指标衡量了该方案的应用价值。 -Discussion based on the zigzag Scrambling MPEG4 video data encryption technology, pointing out that such a program in the security deficiencies, suggestions to improve the program. Improvement program with a different AC coefficient table Scrambling Scrambling, DC coefficient of high-strength encryption algorithm AES encryption. Finally, the effect of the improved encryption, and from the encryption speed, safety and code changes in the three indicators to measure the flow of the program application value. Platform: |

Description: 本文提出将帧内、帧间预测模式置乱, 量化系数与运动矢量加密相结合的H 264 视频加密方法, 试验表
明此方法具有良好的加密效果, 其算法复杂度低, 对编码效率影响小, 适合实时应用 在此基础上我们进一步提出了一
套完整的视频加密系统, 通过将二层序列密钥同步与告知机制相结合的方法实现了快速序列密钥同步, 多用户访问控
制, 并扩大了序列密钥的产生空间, 增加了系统的安全性.-A new video encryption method which utilized Intra, Inter prediction mode scrambling, transform results and mo
tion vector encryption is propo sed in this paper based on the formers research work. Test showed that this method exhibits nice se
curity moreover its computational complexity is rather low, has little impact on encoding efficiency and can be realized in real time
environment. A video encryption sy stem based on the algorithm is also put up, the fast synchronize of the streaming key and multiple
user access is achieved by two level synchronization and telling mechanism. Platform: |
