Abstract: With the development of cloud storage, data security issues in the cloud are becoming increasingly prominent. Aiming at the data security problem in the cloud, a cloud data integrity detection scheme based on linear coding (DISLC) based on linear coding is proposed. The DISLC model combines homomorphic labels and linear network coding. Combined with the characteristics of network coding, a coding method suitable for cloud data protection was designed. This method not only realizes repeated verification of cloud data integrity, but also supports dynamic operation of cloud data. After analysis, this method can not only improve the security and integrity of data in the cloud, but also effectively reduce the computational overhead and communication overhead during cloud storage.

Key words: cloud storage, network coding, repeat verification, integrity verification, dynamic operation
