Identity-based strong designated verifier signature schemes

We should specify a verifier in some circumstances.Using identity-based cryptography,this paper proposed a strong designated verifier signature and a strong designated verifier multi-proxy signature.It also analyzed the proposed schemes.The proposed strong designated verifier signature scheme was lower than Kang et al.'s scheme in the signing cost and verifying cost.The proposed strong designated verifier multi-proxy signature scheme could delegate n proxy signers.Thus it could prevent proxy signers abusing signing authority.
