Exploring the Future of Key Management and Authentication in Public Key Infrastructures

The five-algorithm design in this study covers authentication, advanced key management, post-quantum security, and integrating blockchain. The Lifecycle Management Model Algorithm uses a cyclical process to make encryption keys. This process is built on rotating keys and updating parameters to keep things flexible. Lattice-based encryption is used by the Post-Quantum Encryption Integration Algorithm to protect against quantum threats. For post-quantum security, it is always changing to use technology that is not affected by quantum mechanics. To make a dynamic and reliable authentication system, the Advanced Authentication Protocols Algorithm collects physiological data, looks at behavioral trends, and uses quantum-resistant authentication protocols. Proof of Work and quantum-resistant protections are used by the Blockchain-based Key Management Algorithm to build decentralized trust in key transfers. Lastly, the Scalable PKI Infrastructure Algorithm makes sure that it can grow as needed, respond to new technical settings, and register entities dynamically by combining many technologies. As part of the ablation study, each program was taken apart. Key rotation, behavioral analytics, Proof of Work, and quantum-resistant integration were the main topics of the works. These algorithms keep cryptographic systems safe from new threats and give today's complicated digital ecosystems a flexible base.
