摘要
目前,人们在解决计算机的安全和容错问题时,常常将它们分别进行处理。文章通过网络系统安全和容错模型,提出了在计算机系统中,安全和容错是相互联系和互相影响的。在设计系统时,如果仍然采用传统的方法,将安全和容错孤立起来看待来解决安全和容错问题是不全面的。事实上,安全技术和容错技术的目的和方法有些是相同的。这样的关系要求人们在解决这两个问题时应将它们结合起来加以综合研究。若采取有效的措施解决好这个问题,计算机系统的整体性能将会有很大的提高。
The need for highly secure,highly dependable computer systems is acute in today's world.However,frequently security and fault-tolerance are looked at in isolation to each other,as two separate issues.In this paper,the authors contend that there are areas where the both goals and methods overlap,and that there is a large benefit to be gained by examining the two in relation to one another.This paper is intended to expand on this viewpoint and give convincing arguments for is support.The authors believe that the performance of security and fault-tolerance of the computer system will be enhanced if they consider the impact each can have on the other.
