摘要: 随着信息体系对抗强度的升级,网络空间已演变为由各类信息平台及控制网络互联而成的复杂网电环境,所面临的安全威胁日趋复杂.作为网络空间安全的基石,各类密码算法实现不可避免地受到由环境引入或攻击者恶意施加的故障扰动影响,进而引发密码安全性问题.本文以电压毛刺故障扰动手段为基础,对分组密码算法实现的故障产生机理及安全扰动机制进行了分析和研究;构建了用于刻画密码电路故障传播概率性波动模型;结合不可区分性理论、活动字节传播概率的统计分布技术,提出了能够充分反映故障扰动场景下分组密码实际安全特性的度量框架.实验表明,该度量框架能够充分反映实际故障概率传播特性与攻击者区分优势之间的关联性,并对分组密码实现在遭受故障攻击下的安全性实施客观分析.

Abstract: With the upgrade of the information system confrontation,the cyberspace has developed to a complicated network electricity environment,composed of kinds of interconnected information platforms and control networks.Its security threats has been more complicated.As the security base of the cyberspace,the fault disturbance to the implementation of the cipher,caused by the environment and the malicious attacker,can not be avoided,so the security problem of the cipher will be induced.In this paper,based on the voltage glitch fault injection,the fault generation and the security disturbance mechanism of the block cipher chip,is analyzed.The fluctuant model,used for characterizing the fault propagation probability of the cipher chip,is constructed.Applying the indistinguishable theory,and the statistical distribution of the propagation probability to the active bytes,the metric model of the actual physical security for the block cipher chip,is proposed.It is experimented that,the relevance,between the actual fault propagation probability and the distinguish advantage,can be reflected by the model,so the security of the block cipher,in the scene of the fault attack,can be analyzed objectively.
