The intelligent encryption method of sensitive database based on AES algorithm is put forward, and the security key of information encryption of sensitive database is constructed. Adaptive feature classification and vector quantization coding design for sensitive database storage information are carried out by arithmetic coding design scheme. Under the advanced encryption standard protocol (AES), the cyclic code reconstruction and block encryption design of sensitive database storage data encryption are carried out. The encryption and decryption keys are constructed, and the characters of the decoding plaintext of sensitive database intelligent encryption cyclic codes are reorganized into blocks. The random sampling method is used to reorganize the sample space of the sensitive database to store the information. Combined with the key agreement check and elliptic linear coding, the multi-layer encryption design of the highly sensitive database storage is realized. The simulation results show that this method has strong anti-attack ability and good encryption security, and improves the security of sensitive database storage.
