Therefore, construction of a constant size ring signature scheme without random oracle meeting stringent security requirement still remains as an interesting open problem.  ...  Dodis et al. proposed a constant size scheme in EUROCRYPT'13, but provably secure in random oracle model.  ...  But, their approach uses Fiat-Shamir transformation and provably secure in random oracle model. So the idea of achieving constant-size ring signature without random oracle motivated our research.  ...

This scheme requires that the group (i.e. the ring) is fixed and hence it yields signatures of constant size. The schemes in [37, 54] also yield signatures of linear size.  ...  The scheme in [18] yields signatures of linear size and its security requires both random oracles and the generic group model [51] .  ...  without random oracles.  ...
