Three Party Authentications for key Distributed Protocol using Implicit and Explicit Quantum Cryptography
Abstract:
The combination of 3AQKDP (implicit) and 3AQKDPMA (explicit) quantum cryptography is used to provide authenticated secure communication between sender and receiver.
In quantum cryptography, quantum key distribution protocols (QKDPs) 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 3AQKDP 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 (3AQKDP) 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 (3AQKDPMA) have two 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 with authentication of trusted center.
Disadvantage of separate process 3AQKDP and 3AQKDPMA were provide the authentication only for message, to identify the security threads in the message. Not identify the security threads in the session key.
Software Requirement Specification
The software requirement specification is produced at the culmination of the analysis task. The function and performance allocated to software as part of system engineering are refined by establishing a complete information description as functional representation, a representation of system behavior, an indication of performance requirements and design constraints, appropriate validation criteria.
User Interface
* Swing - Swing is a set of classes that provides more powerful and flexible components that are possible with AWT. In addition to the familiar components, such as button checkboxes and labels, swing supplies several exciting additions, including tabbed panes, scroll panes, trees and tables.
* Applet - Applet is a dynamic and interactive program that can run inside a web page displayed by a java capable browser such as hot java or Netscape.
