Abstract—Proxy multi-signature allows a proxy signer to generate signatures on behalf of a group of original signers. In a designated verifier signature scheme, the signature only can be verified by a designated person. In this paper, we give the model of ID-based designated verifier proxy multi-signature and present a new ID-based designated verifier proxy multisignature scheme. Its security is based on the computational Diffie-Hellman (CDH) problem and it is highly efficient.
Index Terms—proxy multi-signature, designated verifier, ID-based
