Abstract

método de geração de chave de grupo e de gestão para modelo de eventos de comprovação orientado a objeto genérico. a presente invenção refere-se a um método e um aparelho para distribuição de chave de grupo dedicado em sistemas que empregam eventos genéricos da subestação orientados a objeto (goose), e ao dispositivo que facilita o emprego do método. o método compreende definir uma configuração de grupo para o sistema goose, através da sua pluralidade de componentes de dispositivos de campo, verificar a posse por cada dispositivo de campo no referido grupo de um par de chaves assimétricas, distribuir uma chave de grupo individualmente a cada dispositivo de campo membro do grupo por um controlador da subestação através de uma interação segura entre o controlador da subestação e o dispositivo membro do grupo, e atualizar a chave de grupo após a configuração do grupo ter mudado.
