Abstract

With the combination of vector space secret sharing and Chameleon function, a new Chameleon multi-signature based on bilinear pairing is presented in this paper. The scheme has following properties: only the appointed receiver can verify the signature; the appointed receiver can’t disclose contents of the signed information to any third party without the signer’s consent; undeniable; when dispute occur, the signer can prove the signature to be forged without exposure the origin signature; it can protect the signature from allied cheating which comes from in or out the group. With the security analysis, we can conclude that the signature is secure.
