ID-Based Non-Interactive Universal Designated Verifier Signature for Privacy-Preserving Applications

Han-Yu Lin
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, bilinear pairings, privacy-preserving, random oracle, public key system.
