Ring Signature and Identity-Based Ring Signature from Lattice Basis Delegation
Abstract
In this paper, we propose a ring signature (RS) and an identity-based ring signature (IBRS) schemes using the lattice basis del- egation technique due to [10,22]. The schemes are unforgeable and hold anonymity in the random oracle model. Using the method in [28,29], we also extend our constructions to obtain RS and IBRS schemes in the standard model. To the best of the authors' knowledge, our proposed constructions constitute the ¯rst ring signature and identity-based ring signature schemes from lattices
