Abstract

"USO DE ISOGENIAS PARA O DESENHO DE CRIPTOSSISTEMAS". São apresentadas técnicas para prover sistemas de criptografia de chave pública. Mais particularmente, isogenias de variedades Abelianas (por exemplo, curvas elípticas em casos unidimensionais) são utilizadas de modo a prover sistemas de criptografia de chave pública. Por exemplo, as isogenias permitem o uso de múltiplas curvas ao invés de uma curva única a fim de prover uma criptografia mais segura. As técnicas podem ser aplicadas em assinaturas digitais e/ou em soluções de criptografia baseada em identidade (IBE) . Além disso, as isogenias podem ser usadas em outras aplicações, como, por exemplo, em assinaturas cegas, sistemas hierárquicos, ou coisa do gênero. Adicionalmente, soluções são apresentadas para a geração das isogenias.
