Driven by artificial intelligence and network communication technology, intelligent 6G wireless systems have gradually become an important environment for users to enjoy data services in the future. However, edge computing enabled 6G wireless systems still have some open issues on the searchability of outsourced data and security of user information. In this paper, a multidimensional storage structure with encrypted is proposed for data with various categories in intelligent 6G wireless systems. A two-tuple storage table is utilized to compress the block location matrix of the storage structure. Additionally a searchable and secure edge pre-cache scheme is proposed. Edge nodes cache the data requested by the user in advance according to the user’s location and direction. The users in the novel scheme are proved to be unforgeable and anonymous. The experiments show that the scheme is efficient on the user side and the time cost of the edge node indicates that the scheme is low latency.

在人工智能和网络通信技术的推动下，智能6G无线系统逐渐成为未来用户享受数据服务的重要环境。然而，支持边缘计算的 6G 无线系统在外包数据的可搜索性和用户信息的安全性方面仍然存在一些悬而未决的问题。本文针对智能6G无线系统中的各类数据，提出了一种加密的多维存储结构。利用二元组存储表来压缩存储结构的块位置矩阵。此外，提出了一种可搜索且安全的边缘预缓存方案。边缘节点根据用户的位置和方向提前缓存用户请求的数据。新方案中的用户被证明是不可伪造和匿名的。
