自适应多方可解密的勘探开发系统多维加密数据聚合方案OA

The emergence of intelligent oil and gas exploration and development system solves the problems of difficult data analysis and high costs in traditional oil and gas system.However,in the process of real-time collection and transmission,sensitive oil and gas production data are vulnerable to eavesdropping,interception and modification by malicious attackers,which affects the entire industrial field and even the national energy security.Therefore,in order to realize the privacy protection of sensi-tive oil and gas production data,this paper proposes an adaptive multiparty decryptable multidimensional en-crypted data aggregation scheme for exploration and development systems.The scheme modifies double trapdoor homomorphic encryption algorithm to realize data confidentiality,designs the superincreasing sequence to realize the encoding of multidimensional sensitive oil and gas production data,and uses se-cret sharing technique to realize the fault-tolerant transmission function from the smart oil and gas ter-minal to the data aggregation cloud server.The data aggregation cloud server in the scheme can realize the aggregation of encrypted data,and realize the storage of verifiable encrypted data and aggregated ciphertext,so as to reduce the storage pressure of smart oil and gas terminal equipment and control cen-ter.Upon a data request,the smart oil and gas terminal equipment and the control center can use differ-ent keys to decrypt the corresponding ciphertext,and realize the adaptive multiparty decryption func-tion.In the scheme,the data integrity verification is implemented by using hash-based message authen-tication code(HMAC),ensuring lightweight operation.The communication entities that transmit data use anonymous identities for transmission,ensuring data confidentiality while protecting identity priva-cy.The security and performance analysis show that the scheme can ensure the confidentiality and integ-rity of sensitive oil and gas production data,and can be efficiently deployed in smart oil and gas explora-tion and development systems.
