Abstract: Ring signatures can achieve the anonymity of the users who want to sign documents not only in the authenticated way but also in the confidential way. Based on the k-CAA2 assumption, a security designated verifier ring signature scheme is proposed from bilinear pairing. Furthermore, a designated verifier ring signcryption scheme is also proposed from the new designated verifier ring signature scheme.

Keywords: designated verifier ring signatures; ring signcryption; bilinear pairing; k-CAA2 problem; user anonymity; cryptography; signature security; document signatures.
