结合网络编码传输的线性特性,利用信源消息的代数正交补空间的基向量构造了一种适用于网络编码环境下私有认证消息的编码配置方案,提出了一种轻量型的抗污染安全实现方案.分析比较表明,该方案具有计算复杂度低、通信开销小,在应用中具备抗共谋和代间污染的安全性能. Combined with the linearity of network coding transmission, a coding scheme for private authentication message in network coding environment is constructed by using the base vectors of algebraic orthogonal complement space of source message. A lightweight anti-pollution security The results show that the scheme has the advantages of low computational complexity, low communication overhead, and anti-complicity and intergenerational contamination in applications.
