Research of Replication Technology in Intrusion-tolerance System
Hongyan Li · Science Technology and Engineering · 2007
An improvement on passive replication technology is proposed because traditional passive replication can not tolerant Byzantine fault. The model can primary tolerant Byzantine fault. Based on adding hardware check method, overcome shortcomings of passive replication, and taking in advantage of low cost and easy realization of passive replication technology are presented. The credible of group communication always is import and difficult.It is communication message is too large.Base of tradation group communicaton model , design a credible group communication model, the advantage is communication message lower and guarantee that all replicas are consistent at last.
