Abstract

MéTODO PARA ESTABELECER UM CANAL DE COMUNICAçãO ENTRE DOIS NóS EM UMA REDE DE COMUNICAçõES. Método para estabelecer um canal de comunicações seguro utilizando um sistema de chave assimétrica entre um nó inicial e um nó de recepção evita a necessidade que o nó de recepção se comunique com uma terceira parte, com isto reduzindo sinalização.
