摘要
为提高智能电能表数据传输的安全水平,在分析椭圆曲线加密算法原理的基础上,研究了其底层主要组成单元,即基于Galois域乘法器的软硬件设计。针对正规基表示形式的Galois域元素在高维时运算量较大的问题,采用便于硬件实现的多项式基表示法并加入了稀疏元素的判断,进一步减少了计算次数。设计了加密系统在运算和控制方面的整体逻辑架构,将该加密系统应用于智能电能表上,并进行数据破解攻击测试,结果验证了该文方法的可行性。
In order to improve the safety level of data transmission of intelligent electric meter,on the basis of the analysis of the principle of elliptic curve encryption algorithm,study on the underlying main elements,namely the design of hardware and software of finite field multiplier.According to the normal basis representation problem in the finite field elements in the large computation algorithm,using polynomial basis convenient for hardware implementation and joined the sparse representation of elements of judgment,further reduce the number of calculations.The overall logic structure of the encryption system in operation and control is designed.The encryption system is applied to the intelligent electric energy meter,and the attack test of data crack is carried out.The results verify the feasibility of the method.
