Abstract

"CERTIFICAçãO DE TRANSAçõES". O objetivo da presente invenção é gerar e distribuir certificações de maneira segura sem aborrecimentos para o usuário e garantindo os dados de identidade do receptor. Esse objetivo é alcançado por meio de um método de chaves assimétricas, chaves públicas e privadas, entre um centro de chaves e pelo menos uma unidade de usuário, a referida unidade compreendendo um modulo de segurança, o referido método consistindo na geração de certificações compreendendo uma chave pública e uma chave privada, codificação com uma chave de transporte dessas certificações e envio das mesmas para o módulo de segurança de um usuário conhecido, o referido módulo compreendendo a chave de transporte para decodificação da certificação.
