ANALYSIS OF QUANTUM BB84 AND B92 ENCRYPTION ALGORITHMS

Долгочуб Евгений Александрович, Alexey N. Polikanin

A communication channel protected by quantum cryptography cannot be hacked under ideal conditions. But only because there are currently no suitable hacking methods available. All existing methods of breaking cryptographic networks are aimed at mathematical models of ciphers. However, if we follow the rule that the stability of a system is determined by the stability of its weakest link, we can see the opposite. Quantum cryptography is a promising young and developing field in the field of information security. Every specialist in the field of information security is interested in creating a perfect and secure communication network. Systems that currently use the BB84 and B92 protocols are vulnerable to attacks from hackers. These security protocols are already considered outdated, but scientists can not yet offer other options. The article discusses the advantages and disadvantages of the first quantum encryption algorithms BB84 and B92.

Quantum Cryptography: Secure Communication Beyond Classical Limits

Rohit Goyal

Quantum cryptography promises secure communication protocols that surpass the limitations of classical cryptography. By leveraging the principles of quantum mechanics, particularly the phenomenon of quantum entanglement and the uncertainty principle, quantum cryptography protocols offer provable security guarantees against eavesdropping attacks. In this paper, we provide an overview of quantum cryptography, discussing its theoretical foundations, key protocols such as quantum key distribution (QKD), and experimental implementations. We highlight the advantages of quantum cryptography over classical cryptographic techniques and explore its potential applications in secure communication networks, financial transactions, and data privacy. Furthermore, we discuss ongoing research efforts and challenges in the practical deployment of quantum cryptography systems, including the development of robust quantum hardware and the integration of quantum cryptographic protocols into existing communication infrastructures. Overall, quantum cryptography holds great promise for enabling secure communication channels that are resilient to quantum attacks, paving the way for a new era of ultra-secure information exchange.
