A Heterogeneous Database Encryption Algorithm Based on B/S Structure

In order to solve the problem that the key of the traditional method is uneven between the user and the authority center, which leads to the long encryption time of a heterogeneous database, a heterogeneous database encryption algorithm based on the B/S structure is proposed. By comparing the advantages and disadvantages of the C/S structure and B/S structure, the framework of heterogeneous database encryption based on the B/S structure is constructed. Based on the encryption architecture framework of the B/S structure, the key management mechanism is given, and the key of the authority management center at all levels in the server user information management system is generated, as well as the user's key and the user's master key in the corresponding authority center. Combined with the access policy tree encryption to calculate the plaintext data on the server-side of the heterogeneous database, the data that need to be protected is converted into ciphertext form, and the heterogeneous database encryption is completed. The simulation results show that the proposed algorithm can effectively complete the heterogeneous database encryption and protect the database security, and the response time to each service of the database server is shorter than the encryption algorithm compared with the experiment.
