An improved identity-based society oriented signature scheme with anonymous signers

  • Published:
Wuhan University Journal of Natural Sciences

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.
