摘　　要：网格技术是新型的分布计算技术, 是解决复杂度越来越高的新应用的重要方法。信息服务是任何网格软件框架的重要部分,它为发现和监控提供重要的软件机制,也因此为系统的规划应用行为奠定了基础。在此基础上着重讨论了网格信息服务系统的安全和容错的问题,指出网格信息服务系统的安全和容错是相互联系相互影响的,这样的关系要求人们在解决这两个问题时将它们结合起来研究,这样网格信息服务系统的整体性能将会有很大的提高。Grid computing, an important method to solve complex application, is growing more successful in distributed computing. Information services are a vital part of any grid software infrastructure, providing fundamental mechanisms for disco-very and monitoring, and thus for planning and adapting application behavior. After that, the paper importantly talks about the issue of the security and fault-tolerance of the grid information services systems. It seems that the security and fault-tolerance are related and influenced with each other. The authors believe that the performance of security and fault-tolerance of the grid information services systems will be enhanced if they consider the impact each can have on the other.
