摘要:

在云存储应用中,用户文件不在本地存储,因此文件安全性、数据机密性和鲁棒性是关键问题。首先,针对现有文献提出的多个密钥服务器的安全擦除码存储系统未考虑数据鲁棒性导致数据恢复存在缺陷的问题,利用伪随机双线性映射构建云存储完整性检查策略威胁模型;其次,编制接口文件块结构,并参照相关文献算法进行完整性检查方案设计,实现多密钥服务器安全擦除码存储系统算法功能补充,并给出算法计算复杂度分析;最后,实验结果显示,所提出的完整性检查方案可实现较大的数据成功检索概率。

Abstract:

User files are not stored locally in the application of cloud storage, so the key problems include file security, data confidentiality and data robustness. Firstly, according to the security problems of the existing literature, which does not consider data robustness for data recovery, we construct a threat model by using pseudo random bilinear mapping. Secondly, the interface file block structure is prepared, and an integrity check scheme is designed according to the relevant literature algorithm, which can realize the implementation of multi key server security erase code storage system algorithm, and the calculation complexity of the algorithm is given. Experimental results show that the proposed integrity check scheme can achieve a large probability of successful data retrieval.

Key words: cloud storage, robustness, confidentiality, pseudo random, bilinear mapping, secure erasure code
