These are the ancestors of those left behind Yang Gongyuan authentic books on feng shui, the experience is not clear, in the new China, and Xiangxi bandits disturb the baptism of war, but saddened me the most pinworm or 1964 "mini 4 -" 1965 "- senior" and the 1970s when the Cultural Revolution that left a lot of bad feng shui Chinese Book of Changes culture of the ancient books were burned, the present Yang Gongyuan of these books is authentic feng shui to the truth of the sperm of this is grandpa with their lives and will be paid for in Chile, of which a third was burned, photos can be clearly seen.

这几本祖上留下的这些杨公正宗风水古籍书，是经历了清未、民国、新中国、湘西土匪扰乱等战火的洗礼，但最让我家祖伤心的还是一九年"小四清"、一九六五年"大四清"及七十年代文化大革命时候，祖上留下很多中国古代周易风水文化古籍书被烧掉，发上来这几本杨公正宗风水古籍是至精之术的真存本，是爷爷用生命和智慧换来的，其中有一本被烧了三分之一，从照片中可清晰的看到。

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.
