摘要: 为了使可伸缩视频流在异构网络中达到分层安全等级的目的,运用随机函数来随机化视频流各层中的部分数据流,并结合网络编码来抵御已知的明文攻击。此外,对网络编码器进行了研究,设计有序随机线性网络编码器用于可伸缩视频的传输,可以用很少的随机化操作来达到可扩展的安全等级,并降低通信开销。分析表明,所提方案可有效增加网络的吞吐率。
Abstract: With the purpose to achieve hierarchical security levels for scalable video streaming in heterogeneous networks, random function was used to randomize parts of the video streaming in each layer. Network coding scheme was also used to resist known-plaintext attacks. Moreover, network encoder was studied. Ordered random linear network encoder was designed for scalable video transmission. It could achieve scalability in security levels with few random operations and reduce communication overhead. Analysis shows that the scheme could effectively increase the network throughput.
