Research on efficient and secure cross-domain data sharing of IoV under blockchain architecture
To solve the problems of data disclosure, uncontrolled data access, and inefficiency of cross-domain data sharing in the Internet of vehicles (IoV), an efficient and secure cross-domain data sharing scheme of IoV under blockchain architecture was proposed.A blockchain was maintained by trusted autho...

| description | To solve the problems of data disclosure, uncontrolled data access, and inefficiency of cross-domain data sharing in the Internet of vehicles (IoV), an efficient and secure cross-domain data sharing scheme of IoV under blockchain architecture was proposed.A blockchain was maintained by trusted authorities of different trust domains.A modified ciphertext-policy attribute-based encryption scheme was adopted to encrypt data, and encrypted data was stored in interplanetary file system (IPFS) with relevant information recorded on the blockchain, constructing a fine-grained and secure cross-domain data sharing scheme based on blockchain.A verification algorithm for cross-domain access based on the garbled Bloom filter was designed, and a smart contract executed fast decryption tests based on access policies on the blockchain, improving the access efficiency of a mass of ciphertext.A cross-domain data access method based on outsourcing decryption was designed, and the trusted authorities transformed ciphertexts while performing outsourcing decryption with complex bilinear pairing calculations, reducing the time overhead of vehicle decryption.Experiment results show that the proposed scheme is superior to other schemes in the process of cross-domain ciphertext transformation and vehicle decryption, and the cross-domain data access efficiency is increased by 60% on average. |
