摘　　要：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.In order to exploit a lightweight mechanism against pollution, an efficient coding scheme for private authentication information was proposed by combining it with the algebraic characterization of network coding and utilizing the basis vectors of algebraic orthogonal space, which is suitable for net- work coding applications. Analysis showed that the proposed scheme has properties of lower security complexity and bandwidth cost, and is able to resist inter-generation pollution and collusion.
