Abstract

"SISTEMA E MéTODO PARA VERIFICAR ASSINATURAS DIGITAIS EM CERTIFICADOS". Um sistema e método para verificar uma assinatura digital em um certificado, que poderá ser utilizado no processamento de mensagens codificadas. Em uma versão, quando a assinatura digital é verificada com sucesso em uma operação de verificação da assinatura, a chave pública utilizada para verificar aquela assinatura digital é guardada em memória provisória. Quando uma tentativa subseqüente de verificar a assinatura digital é feita, a chave pública a ser utilizada para verificar a assinatura digital é comparada com a chave em memória provisória. Se as chaves casam, a assinatura digital pode ser verificada com sucesso sem exigir que uma operação de verificação da assinatura em que alguns dados são decodificados utilizando a chave pública seja efetuada.
