An Identity Based Strong Bi-Designated Verifier (t, n) Threshold Proxy Signature Scheme
Sunder Lal, Vandani Verma

TL;DR
This paper introduces a novel identity-based threshold proxy signature scheme that allows a group of proxy signers to sign messages on behalf of an original signer, with signatures verifiable only by designated verifiers, enhancing security and control.
Contribution
It proposes a new ID-based strong bi-designated verifier threshold proxy signature scheme, combining identity-based cryptography with threshold and designated verifier features.
Findings
Scheme enables t-out-of-n proxy signing
Signatures are verifiable only by designated verifiers
Enhances security and control in proxy signatures
Abstract
Proxy signature schemes have been invented to delegate signing rights. The paper proposes a new concept of Identify Based Strong Bi-Designated Verifier threshold proxy signature (ID-SBDVTPS) schemes. Such scheme enables an original signer to delegate the signature authority to a group of 'n' proxy signers with the condition that 't' or more proxy signers can cooperatively sign messages on behalf of the original signer and the signatures can only be verified by any two designated verifiers and that they cannot convince anyone else of this fact.
