摘　　要：图像数据库连接外围设备后,容易产生数据泄密或丢失的情况。相关的加密系统受信息隔离效果的影响,导致其存在加密安全性较差,聚合时间过长的问题。为了解决上述问题,设计一种新的图像数据库装载外部数据全同态加密聚合系统。系统硬件由隔离放大器、加密单元和处理器组成。采用IDO-2917型巨磁阻隔离放大器完成信息隔离,利用USB模组和AES加密模组实现数据加密,采用FPGA型处理器进行数据寄存。通过数据滤波预处理、数据特征提取和数据加密聚合实现加密聚合流程。实验结果表明,图像数据库装载外部数据全同态加密聚合系统加密安全性可以达到99%,聚合时间低于2.5 s,具有极好的聚合能力。After the image database is connected to the peripheral equipment,it is easy to cause data leakage or loss.The related encryption system is affected by the information isolation effect,resulting in its poor encryption security and long aggregation time.In order to solve the above problems,a new image database loading external data homomorphic encryption aggregation system is designed.The system hardware consists of isolation amplifier,encryption unit and processor.IDO-2917 giant magnetoresistance isolation amplifier is used for information isolation,USB module and AES encryption module are used for data encryption,and FPGA processor is used for data storage.The encryption aggregation process is realized through data filtering preprocessing,data feature extraction and data encryption aggregation.The experimental results show that the encryption security of the image database loading external data homomorphic encryption aggregation system can reach more than 99%,and the aggregation time is less than 2.5 seconds,with excellent aggregation capability.
