将多样化应用到网络系统、软件中以减少恶意代码传播以及单一重复攻击的多米诺效应是一个广泛的共识。提出一种基于生存能力的节点权值多样化布置算法,从节点重要性出发,将有限的差异系统布置到所有节点中。该算法能在保证单个节点对网络影响最小前提下,实现核心节点的高生存性。仿真实验表明了算法的有效性。
It is a broad consensus to apply diversity to web systems and software to reduce the domino effect of malicious code propagation and single repeat attacks. This paper proposes a new algorithm for node weighting based on survivability. From the node importance, a finite difference system is deployed in all nodes. The algorithm can ensure the survivability of the core node under the premise of ensuring that the single node has the least impact on the network. Simulation results show the effectiveness of the algorithm.
