摘　　要：基于拟态防御构造的多接入边缘计算服务器是一种新型的边缘计算安全系统,拟态防御具有异构和冗余等特性,通过这些特性可以阻断攻击者的攻击,提高系统的安全性与可靠性。在此基础上,提出一种衡量异构性的方法,将执行体集的异构性分解为两部分计算,分别是复杂性和差异性,在理论上为拟态防御的异构性评估上提出一种新方法。实验表明,该方法优于Margalef指数、Shannon-Wiener指数和Simpson指数,更适用于多接入边缘计算中服务器的异构性量化。A multi-access edge computing server based on mimic defense is a new type of edge computing security system.Mimic defense has the characteristics of heterogeneity and redundancy,which can block attackers attacks and improve the security and reliability of the system.Mimic defense mainly used the feature of heterogeneity to greatly improve the security of the system.On this basis,this paper proposes a method to measure the heterogeneity.The method divided the heterogeneity of the execution body set into two parts,namely complexity and difference.In theory,a new method was proposed for the evaluation of the heterogeneity of mimic defense.The experiments show that this method is superior to Margalef index,Shannon-Wiener index and Simpson index,and is more suitable for quantifying the heterogeneity of servers in multi-access edge computing.
