Abstract

"SISTEMAS E MéTODOS PARA A GERAçãO E VALIDAçãO DE ASSINATURAS COM BASE EM ISOGINIA". Técnicas são descritas para a geração e validação de assinaturas. Em uma implementação, um método inclui a geração de uma assinatura pela utilização de uma pluralidade de isoginias incluídas em uma chave privada e incorporando a assinatura e uma chave pública em um produto, no qual a chave pública é configurada para validar a assinatura.
