Practical Cryptographic Strategies in the Post-Quantum Era

摘要

Quantum key distribution technologies promise information-theoretic security and are currently being deployed in commercial applications. We review new frontiers in information security technologies in communications and distributed storage applications with the use of classical, quantum, hybrid classical-quantum, and post-quantum cryptography. We analyze the current state-of-the-art. critical characteristics, development trends, and limitations of these techniques for application in enterprise information protection systems. An approach concerning the selection of practical encryption technologies for enterprises with branched communication networks is discussed.
