Nesta carta, melhoramos o esquema de assinatura de grupo VLR NF'07 (Nakanishi e Funabiki) de modo que ele satisfaça a exculpabilidade e tenha custos de computação mais baixos. No esquema proposto, um membro do grupo gera sua própria chave privada junto com o gerente do grupo, a fim de obter isenção enquanto o tamanho da assinatura não aumenta. Além disso, um novo método de verificação de revogação é proposto na etapa de verificação, e os custos de cálculo da verificação são independentes do número de membros revogados, embora sejam lineares com o número de membros revogados no esquema original. Assim, o esquema proposto é mais eficiente que o esquema original e pode ser aplicável a ambientes móveis como IEEE 802.1x.

Abstract: In this letter, we improve NF'07 (Nakanishi and Funabiki) VLR group signature scheme such that it satisfies exculpability and has lower computation costs. In the proposed scheme, a group member generates his own private key together with the group manager in order to realize exculpability while the signature size is not made longer. Also, a new revocation check method is proposed at the step of verifying, and the computation costs of verifying are independent of the number of the revoked members, while they are linear with the number of the revoked members in the original scheme. Thus, the proposed scheme is more efficient than the original scheme and can be applicable to mobile environments such as IEEE 802.1x.
