摘　　要：围绕一对多通信的隐私保护安全问题,针对通信过程中面临的恶意攻击风险,分析了拦截监听和中断信息两种主流攻击方式。结合两种方式的恶意攻击特点,在分析RSA算法的加解密原理基础上,结合Hash算法和通信消息的确认原理,提出了一种基于Hash算法的消息确认机制。通过对消息确认机制的安全性分析,表明该机制在一对多通信过程中能有效地保障消息传输的安全可靠性,从而达到通信隐私保护的目标。Aiming at the privacy protection security problem of one-to-many communication, this paper analyzes two kinds of mainstream attack modes, such as interception monitoring and interrupt information, aiming at the malicious attack risk in the communication process. Based on the combination of Hash algorithm and communication message, the message recognition mechanism based on Hash algorithm is proposed based on the principle of encryption and decryption of RSA algorithm. Through the analysis of the security mechanism of the message confirmation mechanism, it shows that the mechanism can effectively guarantee the security and reliability of the message transmission in the one-to-many communication process, so as to achieve the goal of communication privacy protection.
