Comparison of classical and quantum cryptography using QKD simulator

In internet and network applications the most challenging aspects is the security. The importance and the value of exchanged data over internet is increasing due to growth in internet and network applications. Cryptography converts the information from normal form to unreadable form, in the computer security. The one encryption algorithm is identified and differentiated from another by two main characteristics that are speed and the efficiency and have the ability to secure the protected data against attacks. Fundamental laws of the quantum physics are applied by Quantum Cryptography to guarantee the secure communication between the legitimate users, namely Alice and Bob. Quantum mechanics is used by Quantum Key Distribution to guarantee the secure communication. This paper provides the comparative analysis on Classical and Quantum Cryptography using various cryptographic algorithms to identify the best algorithm in classical or quantum cryptography.
