Identification and key negotiation between trusted users play a pivot role in generating a session key. The existing protocol uses quantum resources with memory for authentication process but the storage time for qubit is limited. A new mutual authentication quantum key agreement protocol was proposed using Bell pair and the pre-shared key act as the basis for applying bell state measurement without storing the qubit. Security of the proposed protocol depends on inappropriate applying the Bell measurement in different basis leading to entanglement swapping. The participant is able to create a fair session key for each communication and mutually authenticate each identity. The key negotiation and authentication phases of the proposed mutual authentication quantum key agreement protocol have demonstrated that it is unconditional secure.
