区块链、非相似余度以及拟态防御技术已在网络空间不同安全领域得到迅速发展,然而,目前针对这3类创新型技术缺乏有效的模型进行统一描述和分析。采用离散时间马尔可夫链模型进行建模,并对3类系统抵抗攻击或干扰时的性能进行分析,结果表明,拟态防御系统采用动态异构冗余架构与负反馈控制机制能保证系统的高可用性。区块链系统利用高冗余共识机制在一定时间内具有优于拟态防御系统和非相似余度系统的抗干扰性能,但随后性能会快速衰减。非相似余度系统性能随着余度数的增加会快速趋于高余度区块链,系统的抗干扰性能衰减相对缓慢。
Block chain
dissimilar redundancy and mimic defense technology have developed rapidly in different security fields of cyberspace.However
there is a lack of effective models to describe and analyze these three kinds of innovative technologies currently.The DTMC (discrete time Markov chain) was used to model and analyze the anti-interference of the three kinds of systems.The results show that mimic defense system which adopts dynamic heterogeneous redundancy architecture and negative feedback control mechanism can ensure the high availability of the system.The block chain system uses high redundancy consensus mechanism to have a higher anti-interference performance than mimic defense system and dissimilar redundancy system in a certain time
but its performance will decrease quickly after that.With the increase of redundancy
the anti-interference performance of the dissimilar redundancy system will tend to the high redundancy block chain rapidly.Compared with block chain
the anti-interference performance falling of dissimilar redundancy system will be relatively slower.
