Research on Data Integrity Encryption Method of Cloud Storage Users Based on Big Data Analysis

In order to improve the data integrity encryption ability of cloud storage users, a cloud storage user data integrity encryption technology based on random linear coding is proposed. Firstly, the cloud storage user data integrity encryption key of cloud storage user data integrity object is constructed, then the encryption and decryption coding design are carried out, and the random linear coding is used to optimize the digital encryption key to improve the anti-deciphering level. Finally, the simulation results show that the cloud storage user data integrity encryption technology has high random distribution of encryption, the deciphering rate of encrypted data is effectively controlled, and the performance of the cloud storage user data encryption technology is better than that of the traditional method. It effectively ensures the integrity of cloud storage user data.
