A Study on Designated Verifier Signature Schemes and Their Variants

Designated verifier signatures (DVSs) represent a specific type of digital signature that holds significance exclusively for a designated verifier. This feature emphasizes the importance of the intended receiver authenticating the signature, rendering it impenetrable to verification by any other party. DVSs provide a number of potential benefits over standard digital signatures, including increased security, flexibility, and efficiency. This paper conducts a thorough examination of cutting-edge research in the field of DVSs. It digs into the many types of DVSs that have been proposed, including ID-based DVSs, proxy DVSs, designated verifier strong signatures, bi-designated signatures, bi-designated proxy signatures, designated proxy threshold signatures, and multi-proxy signatures and exploration of the several applications that make use of DVS capabilities. In addition, we also propose DVS proxy signature scheme, secure against Type 5 and Type 6 challenger attack.
