一种安全移动会议密钥分配方案

A Key Distribution Scheme of Secure Conference Based on Mobile Network

移动通信已经广泛应用在许多系统中。但无线传播是非常脆弱的,容易被中途截获。已有的方案被证明在抵抗主动攻击和被动攻击时不安全的。给出了一种安全移动会议密钥分配方案。该方案基于模平方根技术,它用于移动通信设备中特别有效,可以有效地实现会议信息的秘密传输与通信主体身份的相互认证。

Mobile telecommunication has been widely used in many fields, but the signal without cable can be eavesdropped easily. The previous scheme is insecure when it is attacked. In this paper, a scheme of distributing conference key based on mobile network is introduced, which is based on the technique of modular square root, make the message of conference is transported securely and all parties involved in conference authentic.
