摘　　要：提出了一种物联网环境下基于身份加密的可搜索数据安全共享方案。该方案将授权用户集合与关键词融合,消除了关键词密文与单个用户的依赖,降低了关键词加密环节的计算开销和通信开销。安全性分析表明,在标准模型下,该方案满足IND-CKA安全性。性能分析表明,该方案的通信开销在关键词加密阶段保持恒定。该方案在关键词加密和搜索陷门测试阶段的计算开销较现有方案有明显降低,更适合物联网环境下云端数据的安全共享。This paper proposes a scheme of secure sharing of searchable data of the identity-based encryption in the IoT environment,which integrates the authorized user set with the keyword,eliminates the dependence of the keyword ciphertext and a single user,and reduces the computing and communication overheads at the link of the keyword encryption.The security analysis shows that the scheme satisfies the IND-CKA security in the standard model.The performance analysis shows that the communication overhead of the scheme remains constant in the stage of the keyword encryption.In the test phases of the keyword encryption and search trapdoor,the computing overhead of the scheme is significantly lower than the overheads of existing ones,which is more suitable for secure sharing of cloud data in the IoT environment.
