Abstract：Under the hard assumption of SIS (Short Integral Solution), a lattice-based ring signature scheme in bonsai tree model is proposed, which based on the bonsai tree signature scheme. Security of proposed ring signature is based on the hardness of SIS. The privacy of signer is guaranteed in proposed ring signature. This ring signature is also unforgeability, which is proved in the standard model (without random oracle).
