Abstract—A Universal Designated Verifier Signature
(UDVS) scheme is an ideal mechanism for preventing any
signature holder from arbitrarily disseminating the signature,
so as to protect the privacy of original signer. Such schemes are
suitable for applications like the certificate of medical records
and income summary, etc. In this scheme, a signature holder
(designator) can generate a designated verifier signature which
can only be verified by an intended verifier. Additionally, the
verifier cannot transfer his proof to any third party, since he is
also capable of simulating a computationally indistinguishable
transcript. In this paper, the author proposes a new ID-based
non-interactive UDVS scheme based on the assumption of
Bilinear Diffie-Hellman Problem (BDHP). To ensure the
security of proposed scheme, the requirement of strong
unforgeability is formally proved in the random oracle model.
Compared with previous works, our mechanism also provides
better functionalities.
Index Terms—Universal designated verifier signature,
