Quantam Computing Using Cryptographic Algorithm

With the growth of quantum computing in power, cryptographic protocols such as RSA and ECC have plenty to worry about with potential attacks that can break security in digital communication. Current research investigates the use of post-quantum cryptography (PQC) in the development of a quantum-resistant chat application centered on Kyber, a lattice-based Key Encapsulation Mechanism, for secure key exchange and AES-256 for message and multimedia encryption. The system to be proposed includes end-to-end encryption, regular renewal of session keys, and metadata privacy for providing a duly secure environment. The solution will render the optimal design so that PQC makes the intended clause of secure messaging quantum-proof in terms of resistance against reasonably plausible quantum attacks. Results support that communication by encryption with the use of Kyber is highly sophisticated in protecting information along with efficiency. Primarily, it discusses the active ciphering restart with the potential of quantum computing. The model functions not only to address the security issue presented by traditional encryption algorithms but also to include highly scalable and fast cryptographic systems that provide a doorway for subsequent communication systems..
