Abstract

"PROCESSO DE FORMAçãO DE CHAVES CRIPTOGRáFICAS E RESPECTIVO COMBINADOR DE DESDOBRAMENTOS". Combinador de desdobramentos de chaves criptográficas, que inclui um certo número de geradores de desdobramentos de chave para geração de desdobramentos de chaves criptográficas e um aleatorizador de desdobramentos de chaves para tornar aleatórios os desdobramentos de chaves criptográficas para produzir uma chave criptográfica; e processo de formação de chaves criptográficas. Cada um dos geradores de desdobramentos de chaves gera desdobramentos de chaves a partir de dados semente. Os geradores de desdobramentos de chaves podem incluir um gerador de desdobramentos aleatórios para geração de desdobramentos de chaves aleatórias baseados sobre dados de referência. Outros geradores de desdobramentos de chaves podem incluir um gerador de desdobramento de sinal para geração de um desdobramento de chave de sinal baseado sobre dados de etiqueta, um gerador de desdobramentos de console para gerar um desdobramento de chave de console baseado sobre dados de manutenção e um gerador de desdobramentos biométricos para geração de um desdobramento de chave biométrica baseado sobre dados biométricos. Todos os desdobramentos podem ainda ser baseados sobre dados estáticos, que podem ser atualizados, por exemplo, por modificação de um número primo divisor dos dados estáticos. Os dados de etiqueta podem ser lidos a partir de um meio de armazenagem e podem incluir dados de autorização do usuário. Os dados de etiqueta podem ser associados a categorias e sub-categorias de destinatários de etiqueta, que são significativos para um usuário que esteja especificando ou determinando o (s) recipiente (s) pretendido (s) da informação ou objeto encriptados. Um arranjo associado a um objeto componente de software pode u sar desdobramentos de chave que determinam que métodos e propriedades são permitidos e controlar o acesso ao endereço de memória para aqueles métodos e propriedades permitidos. A chave criptográfica resultante pode ser, por exemplo, uma corrente de símbolos, pelo menos um bloco de símbolos ou uma matriz de chave.
