摘要： 网络可生存性研究是对传统的安全概念和技术的突破,已经成为网络安全研究的新方向。该文首先分析了可生存性与传统安全概念的差异,通过对网络可生存性研究现状的分析和概括,总结出了可生存性定义要素、测定标准、实现技术及相关研究的一些共识。然后对国外可生存性研究的主要进展——可生存系统分析方法SSA进行了深入探讨,并分析了网络可生存性研究的发展趋势,最后对实现可生存性的两种不同方法进行了对比分析。

Abstract: In contrast to the traditional security concepts and technologies,survivability has become a new direction in network security.Firstly,an analysis of the differences between survivability and traditional security concepts is made.And the paper concludes elements of survivability definition,measurements and computation technologies of survivability,and some common understandings,based on analysis and generalization of current research on survivability,then,introduces the main progress,SSA,short for survivable system analysis,and analyzes development trend of research on survivability,finally,analyzes the differences between the two methods to realize survivable systems.
