In 2003, we succeeded in manufacturing 30 types of K series program-controlled paper cutting machines by using the most advanced techniques in the world. Furthermore, in 2006, the computer-controlled, high-speed, high-accuracy paper cutting machine K-CD series was listed in the National Torch Project. GUOWANG's strategy had led the company to gain more than 10 years of continuous sales increase. In April 2009, we imported 7 sets of CNC pentahedron machining center which lead GUOWANG to be the leading manufacturer of Chinese paper cutting machine industry that owns the largest scale, most complete and advanced machining centers.

从2003年采用国际最先进切纸机生产技术实现生产K系列30种型号程控切纸机到2006年K-CD型电脑程控高精度高速全开切纸机被列入国家火炬项目，我们一直朝这一目标看齐、迈进。2009年4月份我公司又引进了7台进口CNC五面体加工中心生产设备，成为目前全国切纸机行业当中拥有加工中心最齐全，最庞大，最先进的生产商。

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.
