Abstract:

This work presents combination of classical

cryptography (existing) and quantum

cryptography (proposed).

Two three-party QKDPs, one with implicituser authentication and the other with explicit

mutual authentication which is used to make

authentication using quantum mechanism

Introduction:

In classical cryptography provides convenienttechniques that enable efficient keyverification and user authentication but it isnot identify eavesdropping.

Here, the enhanced key distribution protocolusing classical and quantum cryptography

will improve the security and authentication


4/12

Existing System:

In classical cryptography, three-party key distributionprotocols utilize challengeresponse mechanisms ortimestamps to prevent replay attacks .

However, challengeresponse mechanisms require at leasttwo communication rounds between the TC andparticipants, and the timestamp approach needs theassumption of clock synchronization which is notpractical in distributed systems (due to the unpredictable

nature of network delays and potential hostile attacks) . Furthermore, classical cryptography cannot detect the

existence of passive attacks such as eavesdropping.

Disadvantages of Existing System:

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.


6/12

Proposed System:

In quantum cryptography, quantum key distributionprotocols (QKDPs) employ quantum mechanisms todistribute session keys and public discussions to check

for eavesdroppers and verify the correctness of asession key.

However, public discussions require additionalcommunication rounds between a sender and receiverand cost precious qubits.

This section presents a 3AQKDP with implicit userauthentication, which ensures that confidentiality isonly possible for legitimate users and mutualauthentication is achieved only after secure

communication using the session key start. Theproposed three-party QKDPs are executed purely in thequantum channel, and this work does not considererrors caused by environmental noise.
