摘　　要：通信网络中的数据来源广泛,包括用户设备、网络设备、各种应用程序等。这些数据在格式、语义等方面存在很大差异。设计一种既能在加密数据上进行有效检索,又能保证数据安全性的算法是极具挑战性的。传统加密技术虽能保护通信网络中数据免受未授权访问,但加密后数据变得不可搜索,限制了数据的可用性,提出基于可搜索加密的通信网络数据安全检索。基于可搜索加密技术进行通信网络数据加密。通过语义分析技术生成一系列与原始关键词意义相近但字面表达各异的混淆关键词,并将这些混淆项整合至索引体系中,构建更加多维的加密索引结构。最后,利用混淆关键词机制完成通信网络加密数据的安全检索。实验结果表明,设计方法在恶意攻击下检索通信网络数据的成功率高达97.4%,验证了该方法即使面对攻击时也能实现通信网络数据的安全检索。The data sources in communication networks are diverse,including user devices,network devices,various applications,etc.These data have significant differences in format,semantics,and other aspects.Designing an algorithm that can effectively retrieve encrypted data while ensuring data security is extremely challenging.Although traditional encryption techniques can protect data in communication networks from unauthorized access,encrypted data becomes searchable,limiting its availability.Therefore,a secure retrieval of communication network data based on searchable encryption is proposed.Encrypt communication network data based on searchable encryption technology.Generate a series of confused keywords with similar meanings but different literal expressions to the original keywords through semantic analysis techniques,and integrate these confused items into the indexing system to construct a more multidimensional encrypted indexing structure.Finally,utilizing the obfuscation keyword mechanism to achieve secure retrieval of encrypted data in communication networks.The experimental results show that the success rate of the design method in retrieving communication network data under malicious attacks is as high as 97.4%,verifying that the method can achieve secure retrieval of communication network data even in the face of attacks.
