The generalized Jordan derivable mappings at zero point on von Neumann algebra are the sum of an inner derivation and identical mapping produced at a fixed operator,and the similar result is obtained on B.

This paper first analyses and summarizes the ststus quo and evolution trend of encryption, some common used cryptograph are introduced, including the algorithms used in symmetric cryptosystem and asymmetirc cryptosystem. We describe the theory of each algorithms and compare the elliptic curve cryptosystem with the other two asymmetric cryptosystems to show the advantages of this algorithm. Second, the principle of ECC is discussed, including the math foundation of ECC, basic conception of elliptic curves, constructiong idea of ECC, operation on the elliptic curve and so on. Third, the current attacks of ECC were analyzed deeply, and an algorithm based on limited prime number field was constructed. We analyzed its realizability in theory, and implement it by using certain function of MIRACL software package. Latter half in this paper, the implementation model of a simple elliptic curve encryption system which based on GF has been introduced. The paper also put a deep analysis on the algorithm of point addition and point multiplication.

本文首先对密码技术的发展现状及其发展趋势进行了分析和综述，详细的介绍了私钥密码系统和公钥密码系统的发展，说明各种算法的原理和优缺点，并给出了一些典型的密码体制的简要分析，重点将椭圆曲线算法与其它几种公钥密码算法比较，说明椭圆曲线算法的优势；其次，探讨了椭圆曲线密码体制的原理，包括椭圆曲线密码的数学基础、基本概念、椭圆曲线密码体制的构造思想等问题；第三作者对椭圆曲线的攻击现状作了详细的分析，针对所使用的大素数域F_p，设计了素数域上安全椭圆曲线产生的算法，从理论上做了可实施性分析，从软件上做了具体实现；在本文的后半部分，提出了一个简单的基于有限素数域上的椭圆曲线加密方按算实现模型，并对SECES中设计的点加和点乘运算进行了深入分析。

Neither must we attempt to confine the Platonic dialogue on the Procrustes bed of a single idea.

我们也不应该把柏拉图的对话硬行限制在某个概念上，就像把人硬塞到普罗克拉斯提寺的床上那样。

From the concept, it does the exact opposite of a camera: instead of recording an image of the environment by means of an orthographic or perspective projection, projective texture mapping projects an image onto the environment, by using a matrix very similar to the one a camera uses.

从这个概念上，它与摄象机正好相反，不是通过正交或者透视投影来记录环境的图象，而是把图象投射到环境上，通过使用类似于摄象机使用的矩阵。
