Quantum-Enhanced Digital Signatures: A Secure and Scalable Approach for the Post-quantum Era

With the coming of quantum computing, customary computerised signa- ture plans go up against vulnerabilities due to their reliance on classical crypto- graphic assumptions. This examination presents a quantum-enhanced progressed
signature framework that plans quantum key scattering (QKD) and post-quantum cryptographic strategies to ensure secure confirmation and message perception. The method incorporates quantum-resistant hash capacities, secure key exchange through QKD, and a solid affirmation instrument to counter potential quantum ambushes.
The test comes almost entirely from an overhauled security, moved forward affirma-
tion precision, and insignificant affirmation dormancy, making the proposed plan a

down-to-earth course of action for future cryptographic applications. This approachhas vital proposals for secure communications in support, defence, and blockchain
systems in a post-quantum period.
