摘要
针对当前网络编码安全解决方案普遍存在着安全性能不高和缺乏一体化设计等问题,利用网络编码的代数特性和最大距离可分码的设计机理来构造网络安全码和一种信源认证密钥的动态更新技术,实现了一种抗污染和防窃听安全方案,完成了两种安全功能的一体化系统融合。结论表明,与现有多目标安全组合方案相比,该方案不仅具有较低的编码计算复杂度,而且实现了抗共谋和防止代间污染等多种安全性能。
Existing solutions for securing network coding incur either inefficiency in security or integrated design deficiency. To resolve this issue, an efficient network secure code and dynamic design to the source authentication key were constructed by combining the algebraic characteristics of network coding with the maximum distance code design mechanism, and then presented an efficient integrated scheme against wiretapping and pollution attacks. Compared with the simple combination of multi-objective security solutions, the proposed scheme shows to be of lower security complexity, and also has the ability to resist inter-generation pollution and collusion.
