摘要
针对云存储系统由于静态的存储架构和存储模式而带来的安全威胁,提出一种基于再生码的拟态化存储方案。该方案利用网络编码方案将数据存储在云端数据节点上,采用一种基于再生码的拟态变换机制,可根据随机时变因素动态地改变数据的存储状态,且能够保证数据完整性和数据持续可用性。拟态变换机制具有随机性、时变性和动态性,通过增加存储系统的不确定性,可阻断和干扰攻击链,增加了攻击者实施攻击的难度和成本,提高了系统的安全性和可靠性。
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.
