摘要
SITAR(ScalableIntrusion-TolerantArchitecture)容侵系统模型是由美国DARPA支持的一项研究计划,它的目标是保护COTS(Commercial-Of-The-Shelf)服务器,但该模型投票监视器在投票/裁决之前需要进行结果的复杂转换,才能决定结果的发布者,造成系统的代价较高.文章将分组码的特性应用到SITAR容侵模型的投票机制中去,讨论有效避免在SITAR模型中投票监视器在投票/裁决之前需进行结果的复杂转换的方法.
The goal of SITAR (Scalable Intrusion-Tolerant Architecture) project is to protect COTS servers.The SITAR architecture based on an intrusion-tolerance model are decided on a final response through a simple majority voting process for given request.Complex transformations are needed before the voting/adjudication process in the Ballot Monitors can begin.This paper presents major error-control techniques available for voting for SITAR intrusion tolerant model,and discusses an effective method to avoid complex transformations in the Ballot Monitors.
