基于格的分级盲签名

A Hierarchical Blind Signature Scheme on Lattice

在现有的基于身份的盲签名基础上,依据格基扩展算法的特性,提出了格上基于身份的分级盲签名方案,增加了上级签名者对下级签名者权限的有效管理.并验证了正确性、安全性和分级性,效率分析后,得出公钥、私钥和签名长度并无明显增加.

Based on identity-base blind signature,we propose a hierarchical blind signature through lattice expansionalgorithm,which increases permissions management of the subordinate signer to superior signer,and it is the correctness,security and scalability.By efficiency analysis,the lengths of public key,private key and the signature are not significantlyincreased.
