摘　　要：为解决6G移动通信系统中雾无线接入网中数据共享的数据安全问题,提出了一种实现本地差分隐私和动态批量审计的内生安全数据共享机制。首先,用户本地对数据运行RAPPOR算法保护数据隐私;其次,雾接入点对数据进行缓存和预处理;再次,大功率节点对雾接入点上的数据进行基于BLS签名和Merkle哈希树的数据完整性审计;最后,BBU池通过统计分析推断出共享数据的原始分布。安全性分析和仿真表明,所提机制实现了用户的本地差分隐私,并支持安全的多客户端批量审计和数据动态操作,同时具有较高的时间、空间和通信效率。In order to solve the data security problem of data sharing in the fog radio access network in the 6G mobile communication system,an endogenous secure data sharing mechanism that realized local differential privacy and dynamic batch auditing was proposed.First,the user ran the RAPPOR algorithm locally on the data to protect data privacy.Next,the fog access point cached and preprocessed the data.Then the high power node performed a data integrity audit based on the BLS signature and Merkle hash tree on the data cached on the fog access point.Finally,the BBU pool infered the original distribution of shared data through statistical analysis.Security analysis and simulation show that the proposed mechanism realizes the local differential privacy of users,supports secure multi-client batch audit and data dynamic operation,and has high efficiency in time,space and communication.
