移动社交网络中一种朋友发现的隐私安全保护策略
发布时间：2019-07-22 21:24
【摘要】：在移动社交网络中分享用户特征属性配置文件能够迅速找到与用户特征属性相同的朋友。然而,配置文件通常包含用户的敏感隐私信息,如果被恶意攻击者截获将有可能造成不可预计的后果。该文提出一种基于用户伪身份匿名与哈希值比对认证的双重握手机制的隐私保护方案,结合身份权限认证、单向哈希散列函数、密钥协商等技术保证恶意攻击者无法通过身份欺骗、伪造特征属性、窃听安全信道等方式获取用户配置文件的真实内容,从而保证用户的个人隐私不被泄漏。依靠可信第三方服务器强大的计算和抗攻击能力,减轻智能用户终端计算负担和安全风险。安全分析和实验分析表明,该方案更具有隐私性、消息不可抵赖性和可验证性,比传统的解决方案更有效。
[Abstract]:Sharing user feature profiles in mobile social networks can quickly find friends with the same user characteristics. However, the configuration file usually contains sensitive privacy information of the user, and if intercepted by a malicious attacker, it may have unpredictable consequences. In this paper, a privacy protection scheme based on user pseudo identity anonymity and hash value comparison authentication is proposed. Combined with identity authority authentication, one-way hash function, key agreement and other techniques, malicious attackers can not obtain the real content of user configuration files through identity spoofing, falsifying feature attributes, eavesdropping security channels and so on, so as to ensure that users' personal privacy is not leaked. Relying on the powerful computing and anti-attack ability of trusted third-party server, the computing burden and security risk of intelligent user terminal are reduced. Security analysis and experimental analysis show that the scheme is more privacy, message non-repudiation and verifiability, and is more effective than the traditional solution.
