摘　　要：无线技术和智能终端的迅速发展大大推广了位置服务技术的广泛应用。在传统的信息集中式服务器管理下,以服务器作为可信第三方经常出现位置隐私的泄露、位置信息的篡改等问题给用户的隐私安全问题带来了巨大的隐患。因此提出了一种分布式的位置信息共享方案,基于多维虚置换实现各用户之间的位置共享,消除了第三方的存在可能引发的安全隐患,实现了用户的位置信息共享。安全分析表明,在数据安全性、隐私保护方面具有明显的优势。The rapid development of wireless technology and intelligent terminal greatly promote the wide application of location based service tech⁃nology.In the traditional information centralized server management,the server as a trusted third party often causes location privacy leak⁃age,location information tampering and other security issues.It brings huge hidden danger to users’privacy security.Therefore,this paper proposes a distributed location information sharing scheme,which realizes the location sharing among users based on multi-dimensional virtual permutation.It also eliminates the potential security risks caused by the existence of the third party,and realizes the location infor⁃mation sharing of users.Security analysis shows that the scheme has obvious advantages in data security and privacy protection.
