摘要
对移动互联网隐私信息进行加密,为了保障移动互联网中隐私信息采集过程的安全性和完整性。针对现行加密方法应用于移动互联网中根据隐私信息的价值级别选取相应的加密方法,忽略了采集过程中隐私信息的完整性,导致信息加密效果不理想。提出一种新的隐私信息采集过程加密方法。移动互联网下隐私信息根据其属性和采集时间可被划分至多个子空间中,在子空间中对隐私信息进行加密并传输至中继节点上,当中继节点需要读取隐私信息时,需要向数据源节点请求隐私信息相应的子密钥,数据源节点依据自身的策略决定是否授权,确保其生成的全部子密钥的安全性。加密后通过切分重组,将冗长的隐私信息划分为较小的信息切片,通过转换后再进行融合,保证加密后信息的完整性。实验结果表明,所提方法提升了隐私信息采集过程的安全性和完整性。
In this article, we present a method to encrypt private information in collection process. According to the attribute and acquisition time, the private information in mobile Internet was divided into many sub - spaces. In sub - spaces, the private information was encrypted, and then it was transmitted to the relaying node. When the rela- ying node needed to read private information, it needed to request the corresponding sub - key of private information from the data source node. Meanwhile, the data source node determined the authorization according to its own strategy, so as to ensure the security of all sub - keys. After encryption, the lengthy private information was divided into smaller information slices through the segmentation and reorganization. Finally, they were transformed and fused to ensure the integrity of encrypted information. Simulation results show that the proposed method enhances the security and integrity of private information collection process.
