- Abstract
In the research of attribute-based encryption in cloud storage environment, there are some problems such as poor security of the central certification authority, low efficiency, heavy computing burden and cloud data integrity can't be guaranteed. In this paper, we proposed a multi-authorization attribute-base verifiable encryption scheme based on blockchain. This scheme can verify the correctness of keys distributed by multiple authorization centers, thereby solving the problem that all authorization centers need to resend the private key when the wrong key is found; At the same time, based on the traceability and immutability of blockchain, our scheme can perform fine-grained access control and prevent cloud data from being tampered with; Finally, the security analysis proves that the scheme can resist selection plaintext attacks under the random prediction model.
