Resource allocation is the method of providing various available resources to the users in a network. Optical network is the method of the transmission of data through established equipment of optical fiber cables. Optical fibre cable used by different cable industries for communication between digital signal, telecommunication and data cable signals. Because of the low interfering, optical fibre cable has wide variety of applications over copper cable. The previously used techniques, described the distribution of the resource issue over the network for the three kinds of the stations and solution algorithms were proposed to solve the problem. First approach is representing the quantum key distribution that enables two parties to share a random key over the network .Also, different security phases have been demonstrated by updating multiple keys. Proposed algorithm decrease the rate of loss of data during the communication in optical networks. An approach is implemented namely route wavelength and time period arrangement (RWTA) algorithm to assign properties for three kinds of the stations and examine the results based on various structures. The proposed approach is based on two security mechanisms, which are in terms of the quantum key distributions and OSTBC encoding process, to improve the authentication in the network. In addition, quantum key distribution and OSTBC encoding is processed to evaluate the performance of the Quality service channel (QSC) and time division channels (TDC). Finally, it was determined that there is low probability of blocked data and less chances of the key failure in the network.
