Identity Based Strong Designated Verifier Parallel Multi-Proxy Signature Scheme

TL;DR

This paper introduces a novel identity-based scheme enabling a designated verifier to authenticate proxy signatures generated by a group of proxy signers, enhancing security and delegation control.

Contribution

It proposes a new identity-based strong designated verifier parallel multi-proxy signature scheme with specific validation constraints.

Findings

The scheme ensures only the designated verifier can validate proxy signatures.

It supports parallel processing of multiple proxy signatures.

The scheme enhances security in delegated signing scenarios.

Abstract

This paper presents a new identity based strong designated verifier parallel multi-proxy signature scheme. Multi-Proxy signatures allow the original signer to delegate his signing power to a group of proxy signers. In our scheme, the designated verifier can only validate proxy signatures created by a group of proxy signer.
