An Efficient System for Transmission of Data over Network using QKD

Most of the web based applications requires a security for the data. Providing security to the data is a process known as cryptography, which consists of encryption and decryption process. Most of the conventional cryptographic algorithms used in the environments of communication network, based on mathematical models and computational assumptions, are unsafe and apt by many attackers. Problems associated with private-key encryption process is, firstly it depends entirely on the secrecy of the key, secondly it requires two parties who initially shares no secret information to exchange a secret key and an eavesdropper can snoop secret key as it is being exchanged. In Public-key encryption there is no key distribution problem; however, security relies on unproven mathematical assumptions such as the difficulty in factoring large integers. To overcome above mentioned limitations associated with both approaches, we have designed an approach to augment private key encryption with quantum key distribution. Experimental results showed that proposed approach outperforms better than existing approaches.
