移動社交網(wǎng)絡中一種朋友發(fā)現(xiàn)的隱私安全保護策略

【摘要】：在移動社交網(wǎng)絡中分享用戶特征屬性配置文件能夠迅速找到與用戶特征屬性相同的朋友。然而,配置文件通常包含用戶的敏感隱私信息,如果被惡意攻擊者截獲將有可能造成不可預計的后果。該文提出一種基于用戶偽身份匿名與哈希值比對認證的雙重握手機制的隱私保護方案,結合身份權限認證、單向哈希散列函數(shù)、密鑰協(xié)商等技術保證惡意攻擊者無法通過身份欺騙、偽造特征屬性、竊聽安全信道等方式獲取用戶配置文件的真實內容,從而保證用戶的個人隱私不被泄漏。依靠可信第三方服務器強大的計算和抗攻擊能力,減輕智能用戶終端計算負擔和安全風險。安全分析和實驗分析表明,該方案更具有隱私性、消息不可抵賴性和可驗證性,比傳統(tǒng)的解決方案更有效。
[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.
