Byzantine failure or malicious attack reduces cloud storage service reliability of cloud service providers, and proposes a secure and reliable data storage scheme based on cloud computing. The data redundancy of distributed cloud server is increased by the LT code, and the decoding efficiency of data users in the data retrieval stage is improved while guaranteeing the global quasi optimal performance. Use support for public data integrity checking and accurate data repair to prevent data owners from staying online for long periods of time, and to design data repair solutions that enable data repair without generating metadata during service operation. The experimental results show that the communication cost of this scheme increases by 15% compared with the cloud storage scheme based on network coding and RS code, but the efficiency of data retrieval is increased by about 1 time times.
