摘　　要：传统敏感信息加密方法未考虑敏感属性基的检测,导致敏感信息的分解精度较低,加密质量较差,存在加密漏洞较多。提出一种分布式互联网敏感信息属性基加密方法。结合准标志集合关系和垂直分解方式,自动检测出敏感信息属性基,根据敏感信息属性基的检测期望值,分解敏感信息关系,将敏感信息关系分解结果映射到权威认证中心,加密敏感信息属性基,并保存至敏感信息存储设备中,同时利用查询处理,校验保存后敏感信息的加密质量。通过仿真对比实验得出,新方法的属性基检测精度较高,敏感信息关系分解精度高达72%,且加密漏洞逐渐减少,稳定在30个左右,具有较高的加密质量,满足敏感信息隐私安全保护的要求。Traditionally, the encryption method of sensitive information ignores the detection of sensitive attribute bases, resulting in low decomposition accuracy, low encryption quality, and many encryption vulnerabilities. This paper focused on a method of attribute-based encryption for distributed Internet sensitive information. The attribute base of sensitive information was automatically detected by combining the quasi-relation of sign sets and vertical decomposition. According to the expected value of detecting the sensitive information attribute base, the relation of sensitive information was decomposed, and the results were mapped to the authoritative center. The sensitive information attribute base was encrypted and saved into sensitive information storage devices. Meanwhile, it was necessary to check the encryption quality of sensitive information through query processing. Through simulation and experiments, it is concluded that the proposed method has high accuracy in the detection of attribute bases. The decomposition accuracy of sensitive information relation is as high as 72%. The encryption vulnerabilities are gradually reduced to about thirty. Therefore, this method has high encryption quality, which can meet the requirement of privacy protection of sensitive information.
