Abstract

Patente de Invenção: "SERVIDOR E MéTODO PARAPREPARAçãO DE ASSINATURAS DIGITAIS". Paraprocessamento de assinaturas digitais , usando um cripto-sistemada chave pública, é proporcionado um sistema de assinatura digitalconveniente, que facilita o controle de uma chave privada. Combase em um "ID" fornecido por um usuário, a seção de controle dechave de criptografação de assinatura dinâmica 16 obtém dadosde assinatura dinâmica registrada e uma chave privada de umabase de dados de controle 12. Os dados de assinatura dinâmicaregistrada são comparados com dados de assinatura dinâmicaregistrada enviados pelo usuário na seção de verificação deassinatura dinâmica 14. Quando for determinado que são dados deassinatura idênticos, a seção de controle de chave decriptografação de assinatura dinâmica 16 fornece dados demensagem enviados do usuário e a chave privada para a seçãode operação de criptografação 18. A seção de operação decriptografação 18 criptografa os dados da mensagem usando achave privada e envia os dados da mensagem criptografados paraa seção de controle de chave de criptografação de assinaturadinâmica 16. A seção de controle de chave de criptografação deassinatura dinâmica retorna assinados, isto é, criptografados osdados da mensagem ou semelhante para o usuário. O usuário nãoprecisa controlar sua própria chave privada.
