Abstract: 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.
