Abstract:

It is widely believed that diversity in network systems and software will decrease the virulence of malicious codes and the domino effect of singlerepeat attacks. Proposes a survivability based nodeweight diversity deploy algorithm. Starting from node importance, the algorithm assigns distinct software to all nodes. The algorithm can guarantee the minimal impact of a single node on the network systems as well as achieve high survivability of the core nodes. The algorithm is proved to be effective through simulation experiments.

Key words: diversity;weight;survivability
