Scalable Hierarchical Identity-based Signature Scheme from Lattices
Geontae Noh, Ik Rae Jeong
In the paper, we propose a novel adaptively secure hierarchical identity-based signature scheme from lattices.The size of signatures in our scheme is shortest among the existing hierarchical identity-based signature schemes from lattices.Our scheme is motivated by Gentry et al.'s signature scheme and Agrawal et al.'s hierarchical identity-based encryption scheme.
