摘要
针对车联社交网用户交友匹配时隐私泄露的问题,利用无可信第三方服务器的安全协议匹配方法,提出一种交友匹配的隐私保护方案。通过将不经意传输协议、simple和cuckoo哈希算法以及Feistel密码结构相结合,设计一种隐私集合交集协议,保证车联社交网用户个人隐私不被泄露。实验验证和分析结果表明,该方案具有更高的效率,能够防止车联网用户隐私泄露。
To address the problem of personal information disclosure when people make friend in vehicular social network,a privacypreserving scheme for friend matching was proposed without trusted third party server.The main idea of the scheme is to design a new private set intersection protocol using the oblivious transfers,simple hash,cuckoo hash and Feistel-like structure to preserve the privacy of vehicular users.The results of analysis and experiment show that the proposed scheme can realize privacypreserving friend matching and has higher efficiency in terms of computation and communication overhead compared with the existing solutions.
