英文摘要

In ProvSec 2008, Wu et al. constructed two server-aided verification signature (SAV-∑) schemes based on BLS signature. In this paper, we provide a new definition of the security of SAV-∑ against collusion and adaptive chosen message attacks. We founded that Wu et al.'s first scheme is secure, while their second scheme is insecure based on our definition.
