This project presents Quantum Key Distribution Protocols (QKDPs) to safeguard security in massive networks, by mistreatment DES algorithmic rule for secret writing and decryption of .txt file. In this project, secure communication between the sender and the receiver is being created attainable through a trusted center by mistreatment secret key authentication. The trustworthy Center distributes a quantum key to each the sender and also the receiver when the verification of the secret key. The sender encrypts the info and sends to the receiver side solely when getting the quantum key from the Trusted Center. Similarly the decoding method happens. RSA algorithmic rule is getting used for quantum key distribution. and the input txt file is retrieved on the receiver aspect.
