Abstract

"SISTEMA E MéTODO DE SEGURANçA DE DADOS CRIPTOGRAFADOS". Um método para comunicação entre um dispositivo de computador e um servidor confiável é descrito. De acordo com o método da invenção, uma senha não reutilizável (one-time password) para uso na comunicação do dispositivo (105) para o servidor é gerada. O dispositivo (105) gera pelo menos um dado de autenticação de solicitação imediata (107) que inclui uma função de pelo menos uma parte de uma resposta anterior (113) do servidor para a mensagem anterior do dispositivo (105). O servidor então gera pelo menos um dado de autenticação de resposta imediata (113) que inclui uma função de pelo menos uma parte da pelo menos uma senha não reutilizável.
