摘　　要：工业物联网(IIoT)技术使得智慧油气勘探开发系统加速了场区数据汇聚,打破了信息孤岛壁垒,同时勘探开发关键数据的机密性、完整性、认证性等信息安全保障也越来越重要。对此,提出了面向智慧油气勘探开发系统的多维密态数据聚合方案。该方案结合超递增序列,改进了同态加密算法,设计了随机盲化秘密参数,即使解密私钥遭泄露,油气勘探开发系统终端设备传输的重要数据也不会被窃取。可信中心根据勘探开发系统中各通信实体的真实身份产生对应的私钥,彼此可以根据对方的身份灵活地协商可认证的会话密钥,计算基于哈希函数的消息认证码。这样,控制中心可以轻量级地验证数据集成平台服务器发送的聚合密文的完整性,解密各个场区关键数据的聚合值,掌握勘探开发状态参数的平均值,实现对智慧油气勘探开发系统的实时监督与调控。安全性分析和性能评估结果表明,所提方案可以安全高效地部署在智慧油气勘探开发环境。Industrial Internet of Things(IIoT)technologies enable intelligent oil and gas exploration and development systems to accelerate the data convergence and break through the barrier of information islands.Simultaneously,the information security protection of data confidentiality,integrity and authentication in the exploration and development process have become more and more important.Regarding this,this paper proposes a multi-dimensional dense data aggregation scheme for intelligent oil and gas exploration and development systems.The scheme combines super increasing sequence technology,modifies the homomorphic encryption algorithm,and designs random blind secret parameters.Even if the decryption key is leaked,the important data transmitted by terminal equipment will not be intercepted.The trusted center generates corresponding private keys according to the real identity of each communication entity,thus each other can flexibly negotiate the authenticated session keys,calculates message authentication code based on the hash function.The control center can lightweight execute integrity verification of aggregated ciphertext sent from the data integration platform server,decrypt the aggregated value,master the average value of status parameters,and achieve real-time supervision and regulation.The security analysis and performance evaluation show the security and efficiency of the scheme in the deployment of intelligent oil and gas exploration and development systems.
