| 摘 要： | In this paper, we present an improved identity-based society oriented signature scheme with anonymous signers, which satisfies： （1） when members leave or join an organization, the public verification key and the signature verification procedure are unchanged; （2） a user participates in several organizations at the same time, her secret key is only related with her identity. However, no previous schemes have these two properties.

| Abstract: | In this paper, we present an improved identity-based society oriented signature scheme with anonymous signers, which satisfies:
(1) when members leave or join an organization, the public verification key and the signature verification procedure are unchanged,
(2) a user participates in several organizations at the same time, her secret key is only related with her identity. However,
no previous schemes have these two properties.
