Abstract

Security is the most common aspect of today' world, when all things are going to digitize then make them secure over the communication channel has become the prime aim of the digital service providers. Although many encryption and decryption techniques are available in the field of the cryptography, but they all are based on mathematical calculation which are difficult to solve but not impossible. The all existing techniques can be break by using quantum computer and some extra efforts. But Quantum Cryptography that is free from the mathematical calculations and large prime number factorization is solution of this type of problems. Quantum Cryptography based on the laws of physics and quantum mechanics which gives the most secure way of encryption and decryption. In this paper Key Generation and Exchanging of Key is implemented by using Visual Basic software to secure the digital data over the communication channel. Quantum cryptography will use Photons to transmit the information over the channel which are polarized at different orientation which are 00,450,900 and 1350 from sender at some basis and these polarized information is received by second party at other end and receiver will match the received photon with his photon on his basis and matched photons will form the Key, and if anyone try to hack that information both parties will come to know about the hacking.
