Abstract
Only a few ID-based ring signature schemes need a constant number of paring operations so far. In this paper, we present an ID-based ring signature (IDRS) scheme which needs only two pairing operations. Using the new IDRS scheme, we propose an ID-based ring signcryption (IDRSC) scheme. Our IDRS scheme and IDRSC scheme enjoy not only a low computational cost, but also a short ciphertext size. We give the security proofs of the two proposed schemes in the random model.
