摘要:

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 net-works,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 en-coder was designed for scalable video transmission.It could achieve scalability in security levels with few random opera-tions and reduce communication overhead.Analysis shows that the scheme could effectively increase the network throughput.

Key words: security, network coding, scalable video coding, random linear network coding, hash function
