| 摘要: |
| 针对电力物联网智能终端与数据中心通信链路低带宽、高延迟的特点,结合泛在物联的网络环境中数据同步和共享的安全需求,以实现通信资源受限情况下尽量减少更新文件传输代价为目标,设计了一种实现轻量级信息动态安全存储与验证的方法,确保了终端存储设备的信息安全。该方法通过动态证明存储技术对数据中心存储密态文件完整性进行验证,并且支持对密态文件的动态修改处理和增量更新。对于修改的文件,仅传输修改部分的数据块到数据中心完成更新,无需重新上传整个文件,有效降低了验证的计算开销和传输的通信开销。 |

| Abstract: |
| The communication link between the intelligent terminal of the power internet of things and its data center has the characteristics of low bandwidth and high delay. Combined with the security requirements of data synchronization and sharing in the ubiquitous internet of things network environment, based on the goal of minimizing the transmission cost of updated files under the conditions of limited communication resources, this paper designs a method for dynamic secure storage and verification of lightweight information to realize the information security of a terminal storage device. The method verifies the integrity of secret files stored in the data center through dynamic proof of storage (DyPoS) technology and supports their dynamic modification. At the same time, it supports the incremental update of secret files. For modified files, only modified data blocks are transmitted to the data center to complete the update without the need to upload the whole file again, thus effectively reducing the calculation overhead of verification and the communication overhead of transmission. |
