摘　　要：物联网隐私数据共享中,由于远距离的高速跨域问题,在数据共享时存在安全隐患,为此设计考虑属性加密的物联网隐私数据跨域安全共享模型。考虑属性加密方法设计重量级物联网隐私数据属性加密方案,实现数据加密模块的设计。基于区块链技术设计跨域安全共享模块设置三个实体,分别为监管中心、云存储器与联盟区块链,实现数据的跨域共享。在角色信誉评估模块中,考虑角色信誉评估角色的恶意行为实施其信誉评估,将评估结果作为选择数据共享对象时的数据基础。测试结果表明:所构建模型的通信开销较低;在4台普通计算机总跨域距离为200 km时,跨域数据共享时间仅为45000 ms左右;在各阶段其操作数量与加解密时间都较低。Due to the long-distance high-speed cross domain,there are potential risks in the privacy data sharing of the Internet of Things(IoT).Therefore,an IoT privacy data cross domain security sharing model considering attribute encryption is designed.On the basis of considering the attribute encryption method,a heavyweight IoT privacy data attribute encryption scheme is designed to construct the data encryption module.The cross domain security sharing module is designed based on the blockchain technology.In the module,three entities(the supervision center,cloud storage and alliance blockchain)are set up to realize the cross domain sharing of data.In the role reputation evaluation module,the malicious behavior of the role reputation evaluation role is considered to implement the reputation evaluation,and the evaluation results are used as the data basis when selecting data sharing objects.The testing results show that the communication cost of the constructed model is low,its sharing duration of cross domain data is only about 45000 ms when the total cross domain distance of four ordinary computers reach 200 km,and its quantity under operation is small and encryption&decryption time are short in each stage.
