格上无陷门的基于证书盲签名

Certificate-based blind signature without trapdoor on lattices

基于Lyubashevsky的拒绝采样技术,构造一个格上无陷门的基于证书盲签名方案.该盲签名方案避免了使用格上的陷门技术.该方案具备了必要的无条件盲性和不可加一伪造性,所需的存储空间较小,通信量也较小.由于方案使用无陷门技术,故而方案的计算复杂度也较小.

Adapting Lyubashevsky's rejection sampling technique,a certificate-based blind signature scheme without trapdoor on lattices is constructed.This blind signature scheme avoids the use of trapdoors on lattice.This scheme possesses the necessary blindness and unforgeability,and requires less storage space and less traffic.Without trapdoor,the computational complexity of the scheme is small.
