In this paper, we introduce the algorithm of Schoof-Elkies-Atkin to compute the order of elliptic curves over finite fields. We give out a fast algorithm to compute the division polynomial f〓 and a primitive point of order 2〓. This paper also gives an improved algorithm in computing elliptic curve scalar multiplication. Using the method of complex multiplication, we find good elliptic curves for use in cryptosystems, and implemented ElGamal public-key scheme based on elliptic curves. As a co-product, we also realized the algorithm to determine primes using Goldwasser-Kilian's theorem. Lastly, the elliptic curve method of integer factorization is discussed. By making some improvement and through properly selected parameters, we successfully factored an integer of 55 digits, which is the product of two 28-digit primes.

In chapter two, concepts of integrity, integral set and integral number are introduced firstly, and then some relationships between the integrity and some other parameters of graphs are given, then the upper and lower bounds of the integrity are investigated on the basis of integral number determined. The final result is the upper and lower bounds of integral number if the integrity is known.

Consider for example a program that is specified as only having to work with values in the range 0 to 25000; a programmer might reasonably choose to use two-byte integers to represent such values. However, a calculation like "work out 85% of 24760" could cause problems, even though the result (21046) is in range. If the calculation is done by multiplying 85 and 24760, the intermediate result 2104600 is out of range.

考虑一个例子：一个程序被详说明其所处理的数值的范围是0—25000，一个编程者可能选择2-字节整数来表现这个值，然而，一个如，"算出24760的85%是多少"的计算可能产生问题，即使结果（21046）在范围之内，因为如果计算的过程中需要用85乘以24760，那么这个中间值——2104600超出了2-字节整数的范围。
