Simulation of Information Encryption Based on Supporting Verifiable IoT Perception Layer

加密技术提升了物联网感知层信息检索的安全性,但给信息搜索造成了困难,为此提出支持可验证的物联网感知层信息搜索加密算法。部署感知层阅读器位置,令RFID技术在同一时间读取多个标签信息,从读取得到的文档集中提取关键字,生成安全搜索索引,并累加文档与索引集合,计算与搜索请求对应的集合、搜索陷门,根据物联网服务器的辅助值计算出加密搜索与索引结果,实现信息搜索加密处理。实验结果表明,所提方法检索效率高,信息所占空间小,加密效果好。

At present,encryption technology has improved the security of information retrieval in IoT perception layer,but caused difficulties in information search.Therefore,an encryption algorithm for information search in IoT perception layer was proposed based on support verfication.Firstly,the reader was deployed on the perception layer to enable RFID technology to read multiple tags at the same time,and extract keywords from the read document set,thus generating a safe search index.Meanwhile,the document and index set were accumulated for calculating the data set and search trapdoor corresponding to the search request.Moreover,the encrypted search and index results were calculated by the auxiliary value of IoT server.Finally,the information search encryption was achieved.Experimental results show that the proposed method has high retrieval efficiency,small information space,and good encryption effect.
