About a method for distribution keys of a computer network using elliptic curves

The paper presents a distribution method based on elliptic curve public key cryptosystem (ECPKC). The notations used to describe the procedure, some of the relations and the principle of the method are taken from the work of Tsujii, Itohand Kurosawa (1993). The novelty of the proposed method is the use of the elliptic curve chord tangent group law. The most important aspect consists of the forms for the private keys and the public keys. The private keys are ordinary integers and the public keys are points on an elliptic curve. Elliptic curve systems are very good for applications with smart cards and in distributed systems, where computational power and integrated circuit space are limited
