Strongly Unforgeable Ring Signature Scheme from Lattices in the Standard Model by Geontae Noh, Ji Young Chun, Ik Rae Jeong

“…To date, various ring signature schemes have been proposed, all considered to be secure as existentially unforgeable with respect to insider corruption; that is, an adversary who chooses ring-message pairs for which he requests signatures, corrupts honest users, and obtains their signing keys can not produce forgeries for new ring-message pairs. Lattice-based ring signature schemes offer lower computational overhead and security from quantum attacks. …”
