作者主要实现了大随机数的生成、采用整除小素数和勒曼测试法判定素数，可以生成三种不同长度的密钥对( 256位、 512位、 1024位)来满足不同的加密安全等级的需求；加密模块中，选用了二进制序列的乘法方法，实现了大数模幂乘运算；解密模块中，引用了扩展的欧几里德法求逆元，并采用中国剩余定理实现解密过程，大大提高了解密速度。 - The spectral analysis of non - orthogonal functions cannot be obtained by orthogonal integration method . only the spectral analysis of some particular non - orthogonal functions can be realized by integral transformation . thus , the concept of reflection matrix is proposed and the mirror symmetry of spectral analysis for non - orthogonal function is revealed . any element functions whose reflection matrix can be obtained possesses its inverse element function . the spectral vector corresponding to an element function possesses its inverse spectral vector corresponding to the inverse element function . by reflection matrix the mapping relation of element function pair and spectral vector pair can be established . spectral analysis of non - orthogonal functions can be obtained with this symmetry by using the integration method as in the case of orthogonal functions , instead of calculating the inverse matrix as usual . so a convenient and practical method for spectral analysis of non - orthogonal functions is offered
非正交函数不能利用正交积分来实现谱分解.仅有某些特殊的非正交函数可以通过积分变换实现谱分解.本文提出了反射阵的概念,揭示了非正交函数谱分析的镜像对称性.任何能够建立起反射阵的元函数存在着它的逆元函数,并且任何基于该元函数的谱向量同时也存在着基于逆元函数的逆谱向量.元函数对与谱向量对通过反射阵建立映射关系.利用这种对称性,非正交函数可以象正交函数一样使用积分方法获得谱分解结果,而不必使用求解逆阵的方法,从而为非正交函数的谱分解提供了便捷、实用的方法
