| 中文摘要: |
| 针对现有云存储数据持有性验证方法验证效率低的问题，提出一种基于动态布隆过滤器的云存储数据持有性验证方法．首先使用同态哈希函数对云存储数据进行处理，简化客户端计算量；然后第三方验证平台使用数据块标签构造动态布隆过滤器，支持云存储数据的全动态操作；最后通过随机验证路径生成持有证据，增强云存储数据持有性验证的安全性．实验结果表明该方法可有效减少证明计算开销，提高了验证安全性和验证效率． |
| 英文摘要: |
| In order to solve the inefficient verification problem of provable data possession in cloud storage, a cloud storage data possession verification method is proposed based on dynamic Bloom filter. Firstly, the homomorphic Hash function is used to process the cloud storage data, which simplifies the calculation of the client. Then, the third party verification platform uses the data block tags to construct the dynamic Bloom filter, which can support full dynamic operation. Finally, the ownership proof is generated by the random verification path, which enhances the cloud storage data possession verification security. The experimental results show that the proposed method can reduce the proof calculation overhead, enhance the verification security and efficiency. |
