Abstract: There are many cases of attribute revocation in the database. When encrypting database, attribute revocation affects the effect of data byte recursion. In order to improve the efficiency of attribute based encryption, an attributebased encryption method for sensitive information ubiquitous in sensor networks is proposed. Estimate the data scale of sensor network nodes, normalize the relevant information, and establish mapping conditions between attribute bases. Select the sensitive information attribute of the data center, control the data byte recursion, randomly match the selected value of the channel, and develop the attributebased encryption scheme. Set the sensing network’s operating parameters, introduce the information structure of the data center, and apply the encryption method based on the cipher text strategy, the encryption method based on the Internet of things, and the designed encryption method to participate in the test. The test results show that the designed encryption method has the lowest encryption time and the best timeliness.Key words sensor network; data center; sensitive information; attribute based; attribute revocation; byte recursion

摘要： 数据中台内属性基存在较多的属性撤销情况，在对其加密处理时，属性撤销影响数据字节递归效果.为了提升属性基加密的效率，设计泛在感知网络应用下的数据中台敏感信息属性基加密方法.预估感知网络节点数据规模，归一化处理相关信息，在属性基之间建立映射条件.选取数据中台敏感信息属性，控制数据字节递归，随机匹配选择信道的选择值，制定属性基加密方案.设置感知网络运行参数，引入数据中台信息结构，应用基于密文策略的加密方法、基于物联网的加密方法以及所设计的加密方法进行测试.测试结果表明：该加密方法的加密时间短、时效性佳.关键词感知网络；数据中台；敏感信息；属性基；属性撤销；字节递归
