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.

This paper focuses on the node stability of eco\|industrial symbiosis system from the view of environmental economics, and set up the Node Symbiotic Economics Model on the enterprises of eco\|industrial symbiosis system by analyzing relationship on the pollutants recycle of the inter\|node interconnected enterprises. Through the observation of the supply change in the enterprise′s recycling contaminants at the node based on the mathematical solutions to the model, the effects of outside disturbances on the balance of supply and demand has been studied. If the elasticity of the product price is equal to or less than 1, the node can achieve conditional stability and if the elasticity of the product price is more than 1, the node will fluctuate periodically around a stable point, and even chaos can appear.
