Abstract:

Aiming to solve security threats in the cloud storage system due to static storage architecture and storage mode,a mimic storage scheme based on regenerated code was proposed.The scheme used network coding scheme to store the data in the cloud data node,and used mimicry transformation mechanism based on regeneration code to change data storage state dynamically according to the random time-varying factors,which could guarantee data integrity and data availability continuously.The mimicry transformation mechanism is a random,time-varying and dynamic scheme,which increases the uncertainty of storage system.It blocks and interferes with the attack chain,increases the difficulty and cost of the attack operation,and improves the security and reliability of the system.

Key words: mimic, network coding, regenerated code, cloud storage
