Digital signatures is a cryptographic protocol that can provide the added assurances of identity, status, proof of origin of an electronic document, and can acknowledge informed consent by the signer. Lattice based assumptions have seen a certain rush in recent years to fulfil the desire to expand the hardness assumption beyond factoring or discrete logarithm problem on which digital signatures can rely. In this article, we cover the recent progress made in digital signatures based on lattice assumptions. The article briefly discusses the working of each signature scheme, then investigates the progress made in recent years and compare them with different aspects of security and efficiency. Besides, it provides some future direction which can be helpful in future work in this area.
