功耗分析平台中混合编程的应用研究

Approach on Hybrid Programming Technique Applied in Power Analysis Attack System

功耗分析平台是有效实施功耗分析攻击的工具,需要服务器与示波器等多种外设进行通信,同时还需要处理大量高维数组并且要求有良好的可操作性,如果采用单一编程语言来开发,则存在功耗分析攻击效率较低的问题。针对该问题,提出了一种新的解决方法,将Java、C++和Matlab这3种编程语言结合,在功耗波形采集、波形特征处理等方面采用混合编程技术进行开发,充分发挥这3种编程语言各自的优势。实验结果表明,在保证功耗分析攻击准确率的基础上,攻击的效率比采用单一语言编程时提高了30%以上。

Power analysis system is the right tool for power analysis attack.To accomplish the attacks properly,it needs the PC server communicates with different types of peripheral devices such oscilloscope.And it requires to disposal of mass of high dimension arrays with good operation-ability.Programming with unique programming language would lead to deficiency of power analysis attack.A new method was proposed by hybrid programming of Java,C++ and Matlab,which took the advantages of all these languages.Experiments showed that more than 30% attack efficiency increased and with no accuracy deficiency by using our method.
