In implicit quantum key distribution protocol(3AQKDP) have two phases such
as setup phase and distribution phase to provide thrce party authentication with secure session key
distribution. In this system there is no mutual understanding between sender and receiver. Both
sender and receiver should communicalc over trusted center.
In explicit quantum key distribution protocol (3AQKDPMA) have two phascs 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

security
is a

priority.
In some key distribution protocols, two users obtain a shared session key via a trusted center
(TC). Since three parties (tw users
and one
TC) are
involved in session
key negotiations, these
protocols are called three-party key distribution protocols, as in contrast
with two-party protocols where only the sender and receiver are involved in session key
negotiations. In classical eryptography, three-party key distribution
protocols utilize challengeresponse mechanisms or timestamps. However, challengeresponse
mechanisms require at least two communication rounds between the TC and participants, and the
timestamp approach needs the assumption of clock
synchronization which is not practical 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 cavesdropping. On the contrary, a quantum
channel
eliminates
eavesdropping, and, therefore, replay
attacks. This fact can then be used to
