摘　　要：利用当前方法对移动互联网敏感信息安全检索时,忽略了对敏感信息的提取,不同类别的索引信息检索效率低、信息的正确检索量偏少。现提出多阶段攻击下移动互联网敏感信息安全检索方法。分析攻击者多阶段攻击行为,并以此为基础提取攻击行为下的敏感信息。设置加密密钥,构建贝叶斯网络信息检索模型。将模型中的敏感信息结点重新组成,根据重新组成的敏感信息结构,获取敏感信息权值,完成多阶段攻击下移动互联网敏感信息的安全检索。实验结果表明,所提方法的索引信息检索效率和正确检索数量均较高,验证了提出方法的精度高、安全性较强。In current methods, the extraction of sensitive information on mobile Internet is often ignored. In addition, the retrieval efficiency of different types of index information is low and the amount of correct retrieval is too small. Therefore, a method of secure retrieval for sensitive information on mobile Internet under multi-stage attacks was proposed. At first, the attacker’s behavior of multi-stage attacks was analyzed. on this basis, the sensitive information under the attack behavior was extracted. Moreover, the encryption key was set up, and the Bayesian network information retrieval model was constructed. Furthermore, sensitive information nodes in the model were reconstituted. According to the structure, the weight of reconstituted sensitive information can be obtained. Finally, the secure retrieval of sensitive information on mobile Internet under multi-stage attack was completed. Experimental results show that the retrieval efficiency and correct retrieval quantity of the proposed method are both high. In addition, the method has higher accuracy and security.
