分配一个会话密钥安全地在真正的用户，班尼特和Brassard投射的三个基本假设的设计工作中的犹豫和4qubit态量子测量。为了在真实用户之间创建会话密钥，班尼特使用了两个无正交量子比特态。基于EPR（爱因斯坦-波多尔斯基-罗森）的量子密钥分配协议提供Ekert，需要回忆来保护真正的参与者比特。即使创建一个会话密钥，而不主要分发密钥，它同意真正的用户，因此，它不需要一个可信中心（TC）。维护和计划的安全是基于对已验证的用户的猜测。然而，这些协议可能遭受中间人攻击不被任何猜测。量身定制的量子密码协议，需要每个垛的用户分发密钥之前选择的测量基hwangetal计划。另一方面，为了确认会话密钥的正确性，用户必须进行公众协商。每个用户和受信任的中心（TC）要共享前一系列的EPR对比密钥。针对上述要求的三方量子密钥分发协议。因此，爱因斯坦-波多尔斯基-罗森（EPR）对计算和上瘾，和可信中心（TC）和用户应该重建后，一个量子密钥分配执行。

To allocate a session key safely among genuine users, the Bennett and Brassard have projected the three essential hypothetical designs in work the hesitation of the quantum measurement1 and 4qubit states. To create a session key among genuine users the Bennett used two no orthogonal qubit states. Based on EPR pairs (Einstein- Podolsky- Rosen) the quantum key distribution protocol offered by Ekert, which needs recollections to protect qubits of the genuine participants. Even though, to create a session key without primarily distributing secret keys it agrees genuine users and for this it do not necessitate a trusted centre(TC). The security is maintained and planned is based on the guess of the authenticated users. However, These protocols might be suffer by the man in the middle attacks without any guesses by the participants.Tailored quantum cryptography protocol planned by the hwangetal that needs each duo of users to distribute a secret key before to selection by measuring bases. On the other hand, to confirm the exactness of the session key the users have to do the public negotiations. Each user and the trusted centre (TC) want to share before series of EPR pairs than the secret key. The three party Quantum Key Distribution Protocol projected for the above requirement. Accordingly, Einstein- Podolsky- Rosen(EPR) pairs are calculated and addicted, and the trusted centre(TC) and the user should reconstruct after one quantum key distribution execution.
