"WebIn this paper, we propose a new two-party adaptor signature scheme that relies on quantum-safe hard problems in coding theory. The proposed scheme uses a hash-and-sign code-based signature scheme introduced by Debris-Alazard et al. and a code-based hard relation defined from the well-known syndrome decoding problem.

It is based on "hash-and-sign" (contrasting Fiat–Shamir transformation) methodology, and claims to achieve smaller signature size. NTRUSign is under consideration for standardization by the IEEE P1363 working group. [citation needed]
