A Low-latency Secure Data Outsourcing Scheme for Cloud-WSN
This work addresses security and efficiency issues for cloud-WSN applications, but it appears incremental as it builds on existing CP-ABE methods with parallel processing optimizations.
The paper tackles the challenge of maintaining data security and processing efficiency in cloud-WSN by proposing a CP-ABE-based data outsourcing scheme that reduces overall data processing time, with performance evaluation showing dramatic improvements compared to traditional methods.
With the support of cloud computing, large quantities of data collected from various WSN applications can be managed efficiently. However, maintaining data security and efficiency of data processing in cloud-WSN (C-WSN) are important and challenging issues. In this paper, we present an efficient data outsourcing scheme based on CP-ABE, which can not only guarantee secure data access, but also reduce overall data processing time. In our proposed scheme, a large file is divided into several data blocks by data owner (DO) firstly. Then, the data blocks are encrypted and transferred to the cloud server in parallel. For data receiver (DR), data decryption and data transmission is also processed in parallel. In addition, data integrity can be checked by DR without any master key components. The security analysis shows that the proposed scheme can meet the security requirement of C-WSN. By performance evaluation, it shows that our scheme can dramatically improve data processing efficiency compared to the traditional CP-ABE method.
