In this paper, the problem of carbon emission data sharing using blockchains is studied.To avoid data leakage, the data is usually encrypted before uploading to the blockchain.To enable flexible searching, a symmetric key searchable encryption is applied, where the blockchain can transform any index ciphertext into a searchable one.We give a rigorous system model and related security definitions.We also analyze and evaluate the performance of our scheme.The results of our experiments show our scheme is secure and efficient.
