Lattice-Based Identity-Based Blind Signature Scheme in Standard Model
摘要
Abstract
The blind signature scheme in the random oracle model relies on the random oracle assumption. The scheme is proven to be secure in theory, but it may not be secure in practice. This paper constructs an identity-based blind signature scheme with lattice in the standard model. A short basis delegation algorithm is introduced to generate the private key. The signature of the message is generated by the forward sampling algorithm proposed by Gentry et al. Under the standard hardness assumption of the small integer solutions problem (SIS), the new scheme is proven to be one-more unforgeable based on Juels and Pointcheval's security model in the standard model. The comparison results show that the key length and signature length are shorter, and the efficiency is higher.关键词
