摘要:

为了丰富用户的位置信息的表现模式,适应多样化的用户需求,基于属性加密设计了一种支持精确、较精确、模糊以及不公开位置信息共4种模式的位置隐私保护方案。以WT-CP-ABE算法为基础,将位置信息根据好友的亲密度等级分成3个部分。采用属性加密和对称加密的方法分别对密钥信息和位置信息进行加密,在社交网络上发布。对方案的安全性进行分析,表明方案具有用户属性信息机密性、数据机密性和可抵抗合谋攻击的优点。

Abstract:

In order to enrich the performance of the user's location information and to meet the diverse needs of users,a location privacy protection scheme based on attribute encryption was designed,which provided precise,more accurate,fuzzy and private four modes to manage the location information.The scheme was based on the algorithm of WT-CP-ABE.The location information was divided into three parts according to a close friend of grade,then the key infor-mation and position information was encrypted with attribute-based encryption and symmetric encryption method respec-tively and the ciphertext was published to the social network.The security of the scheme is analyzed,which shows that the scheme has the advantage of user attribute information confidentiality,data confidentiality and can resist the collusion attack.
