English abstract Recently, the certificateless public key cryptography (CLPKC) has been studied widely since it could solve both of the certificate management problem in traditional public key cryptography (TPKC) and the key escrow problem in the identity-based public key cryptography (ID-based PKC). To satisfy requirements of different applications, many certificateless blind signature (CLBS) schemes using bilinear pairing for the CLPKC setting have been proposed. However, the bilinear pairing operation is very complicated. Therefore, the performance of those CLBS schemes is not very satisfactory. To solve the problem, we propose an efficient CLBS scheme without bilinear pairing. Performance analysis shows that the proposed scheme could reduce costs of computation and storage. Security analysis shows the proposed scheme is provably secure against both of two types of adversaries
Portuguese abstract Recentemente, a criptografia de chave pública sem certificado (CLPKC) tem sido amplamente estudada, uma vez que poderia resolver o problema de gerenciamento de certificados na criptografia de chave pública tradicional (TPKC) e o problema chave de escrow da criptografia de chave pública baseada em identidade (ID-based PKC). Para atender aos requisitos de diferentes aplicações, têm sido propostos muitos sistemas de assinatura cega sem certificado (CLBs), sistemas que utilizam o emparelhamento bilinear para a configuração de CLPKC. No entanto, a operação de emparelhamento bilinear é muito complicada. Portanto, o desempenho desses regimes CLBs não é muito satisfatório. Para resolver o problema, propomos um esquema de CLBS eficiente sem emparelhamento bilinear. Uma análise de desempenho mostra que o esquema proposto poderia reduzir os custos de computação e armazenamento. Uma análise de segurança mostra que o esquema proposto é comprovadamente seguro contra dois tipos de adversários
