一种基于身份的全同态签名方案
发布时间：2018-12-06 19:43
【摘要】：全同态签名方案在可验证外包计算等领域具有重要应用,但目前人们还没有提出基于身份的全同态签名方案.因此,本文给出了基于身份的全同态签名方案的安全定义,基于格问题构造了一个基于身份的层次型全同态签名方案,在标准模型下基于小整数解问题难解性严格证明了所提全同态签名方案满足选择性身份与选择性消息数据集合攻击下的存在性不可伪造性.
[Abstract]:Full homomorphic signature schemes have important applications in the field of verifiable outsourced computing, but no identity-based full homomorphic signature schemes have been proposed. Therefore, the security definition of identity-based all-homomorphism signature scheme is given, and an identity-based hierarchical homomorphic signature scheme is constructed based on lattice problem. In the standard model, it is proved strictly that the proposed full homomorphism signature scheme satisfies the existence unforgeability under the attack of selective identity and selective message data set based on the problem of small integer solution.
