Abstract
A novel ring signature is constructed based on Garg-Gentry-Halevi (GGH) graded encoding system which is a candidate multilinear maps from ideal lattice, and we prove its security in standard model. Under the GGH graded decisional Diffie-Hellman (GDDH) assumption, the proposed ring signature guarantees the anonymity of signer. At the same time, the ring signature is the existentially unforgeable against adaptive chosen message attack under the GGH graded computational Diffie-Hellman (GCDH) assumption.
