Security in Large Networks Using Mediator Protocols projects main aim is to provide security for large scale networks using quantum key distribution protocol and two cryptography techniques( classical and quantum). In this project we use two protocols in which one works on implicit user authentication and other with explicit authentication.
- In classical cryptography replay attacks are solved by using challenge response mechanism.
- In practical situations using Challenge response mechanism is not efficient. In order to communicate between TC and participants we need two communication rounds between them.
- Because of above mentioned reasons it is not possible to prevent eaves dropping attacks using classical cryptography.
