A Practical Lattice-based Ring Signature Scheme

摘要：

In this paper, we propose a new lattice-based ring signature scheme and its security can be reduced to a well-known signature scheme, NTRUSign. This new ring signature greatly decreases the key space and the signature length comparing with the existing latticebased ring signature schemes. Our scheme is suitable for mobile lightweight device, such as smart cards, cell phone, and RFID tokens.
