英国管理学论文代写:密钥共享协议

密钥共享协议用于协助在通信网络中的参与者之间分配专用会话密钥。受保护的公共网络与这些分布式会话密钥之间的发送者和接收者之间的通信是可以实现的。相反,在创建严重的密钥分配协议时会出现许多麻烦。例如,从密钥共享过程中,一个讨厌的攻击者可以演变会话密钥。真正的用户不知道接收到的会话密钥是否正确或错误。而且真实用户不能证明其他用户的唯一性。在通信安全中,设计安全密钥分发协议是一个优先考虑的问题。TC(可信中心)在一些密钥分发协议中为两个用户提供分布式会话密钥。在这个过程中共有三方混淆。他们是两个用户和一个可信中心(TC)。这些三方积极参与会话密钥传输。这三个协议,它们是发送者,接收者和一个可信中心(TC)被称为三方密钥共享协议。但在两方协议中,涉及双方的是发送方和接收方。这两个发送者和接收者都涉及在会话密钥交换。三方密钥共享协议在古典密码学挑战-响应机制或时间戳的使用。

Key sharing protocols are used to assist distributing private session keys among the participants in communication networks. Protected communication between the sender and receiver is achievable on anxious public networks with these distributed session keys. Conversely, in badly created key distribution protocols many troubles will arise. For example, from the key sharing procedure a nasty attacker can evolve the session key. The genuine user does not know whether the received session key is right or wrong. And also the genuine user cannot prove the uniqueness of the other user. In communication security the designing secure key distribution protocols is a top precedence. The TC (trusted centre) provides a distributed session key to the both users in some key distribution protocols. There are totally three parties mixed up in this process. They are the two users and one trusted centre (TC). These three parties actively participate in session key transferences. These three protocols they are sender, receiver and one trusted centre (TC) are together called as three party key sharing protocols. But where as in two party protocols two parties are involved they are sender as well as receiver. These two sender and the receiver are pertained in session key exchanges. The three party key sharing protocols make use of challenge response mechanisms or timestamps in the classical cryptography.
