Notes | 51-1196/TP signature ; identity-based; strong, unforgeability; lattices Identity-based signature (IBS) schemes can be widely used in the resource-constrained applications, such as mo- bile e-commerce. At first, it constructed a new lattice based IBS scheme by using trapdoor generation algorithm GenTrap, pre- image sampling algorithm SampleD, and trapdoor delegation algorithm DelTrap which were proposed on Eurocrypt 2012 by Micciancio and Peikert. Secondly, it proved the proposed scheme to satisfy the strong unforgeability against selective identity and static chosen message attacks under the small integer solution assumption in the standard model. Finally, the computing performance of the proposed scheme was compared with the existing lattice based IBS schemes. The comparison result shows that the proposed scheme enjoys the highest computation efficiency.
