Sreeparna Chakrabarti · International Journal of Advanced Trends in Computer Science and Engineering · 2020
The encryption process of Symmetric Key Cryptography is quicker as compared to Asymmetric Key Cryptography, but the key exchange process is a challenge.This paper focuses on Quantum Cryptography techniques for that purpose as traditional digital cryptography techniques are not safe.In "Quantum Key Exchange" Technique, "Heisenberg uncertainty principle" and "quantum no cloning theory" are used to resist attacks.The Quantum Key Exchange is demonstrated through BB84 algorithm and the result is analyzed.Discussion is made on the practical applications of the technique
