Abstract

Patente de Invenção: <B>''PROCESSO PARA O GERENCIAMENTO DE CóDIGOS CIFRADOS ENTRE UMA PRIMEIRA UNIDADE DE COMPUTADOR E UMA SEGUNDA UNIDADE DE COMPUTADOR''<D>. O processo é dividido em fases moduladas individuais. Durante uma autenticação da primeira unidade de computador (C1) e da segunda unidade de computador (C2) são trocadas referências de autenticação (ARA, ARB) que são empregadas em outras fases de cifragem (SP, SA). Com isso, e pela montagem modular não é mais necessária cada nova autenticação normalmente necessária nas outras fases de cifragem (SP, SA) e, portanto, também não é realizada.
