Secured Communication Protocol via Encrypted Key Ensuring Message Integrity

The Secured communication protocol via encrypted key ensuring message integrity combination of Authentication of Third Party Authentication Quantum Key Distribute Protocol (implicit) and Third Party Authentication Quantum Key Distribute Protocol Mutual Authentication (explicit) quantum cryptography is used to provide authenticated secure communication between sender and Receiver. In quantum cryptography, quantum key distribution protocols employ quantum mechanisms to distribute session keys and public discussions to check for eavesdroppers and verify the correctness of a session key. However, public discussions require additional communication rounds between a sender and receiver. The advantage of quantum cryptography easily resists replay and passive attacks. A Third Party Authentication Quantum Key Distribute with implicit user authentication, which ensures that confidentiality, is only possible for legitimate users and mutual authentication is achieved only after secure communication using the session key start. In implicit quantum key distribution protocol Third Party Authentication Quantum Key Distribute have two phases such as setup phase and distribution phase to provide three party authentications with secure session key distribution. In this system there is no mutual understanding between sender and receiver. Both sender and receiver should communicate over trusted center. In explicit quantum key distribution protocol Third Party Authentication Quantum Key Distribute Mutual Authentication have phases such as setup phase and distribution phase to provide three party authentications with secure session key distribution. I have mutual understanding between sender and receiver. Both sender and receiver should communicate directly authentication of trusted center. Disadvantage of separate process 3AQKDP and 3AQKDPMA were providing the authentication only for message, to identify the security threads in the message. Not identify the security threads in the session key.
