摘　　要：针对当前社交网络个人隐私信息泄露的问题,面向P2P社交网络提出一种匿名公钥广播加密方案,包括初始化公钥,分发私钥,加密和解密。并在Android平台下设计实现了基于广播加密的P2P社交网络系统,系统主要包括数据存储模块,移动终端模块,安全加密模块以及PKG管理模块。同时对Android平台下的P2P社交网络在恶意用户截获私聊攻击,恶意下载攻击,篡改攻击和重放攻击的安全性进行了分析,分析结果表明该系统安全可靠。Aiming at the problem of personal privacy information disclosure in social network,an anonymous public key encryption scheme is proposed for P2P social network. The scheme includes public key initialization,private key dispensation,encryption and decryption. And the P2P social network system based on broadcast encryption is designed and implemented in the Android platform. The system mainly includes data storage module,mobile terminal module,security encryption module and PKG management module. At the same time,it analyzes the security of P2P social network in the Android platform in the malicious user intercepting the private chat attack,malicious download attack,tamper attack and replay attack,and the results show that the system is safe and reliable.
