Abstract

In the practical application of identity-based aggregated signature schemes, the problems of singer’s key loss and signer’s identity invalidation often occur. This makes the identity-based aggregate signature scheme need to realize the revocation of the signer, and the existing revocation of identities method needs to rebuild the system master key. Combined with the revocation method proposed by Boldyreva [1], this paper improves the aggregated signature scheme to realize the dynamic revocation of singer’s identities. At the same time, in order to deal with the threat brought by the development of quantum computer to the traditional cryptosystem, a lattice-based aggregate signature scheme based on revocable identity is proposed in this paper.
