摘　　要：现行系统在教学资源数据库安全存储中的应用效果较差,不仅数据存储写入速率较慢,而且数据存储安全系数低。对此,研究基于同态加密的教学资源数据库安全存储系统设计。首先,在系统硬件方面对数据转换器和数据存储器选型进行了优化;其次,在系统软件方面,利用同态加密技术生成数据密钥,对教学资源数据加密后存储到数据库中;最后,进行实验验证。实验证明,设计系统数据存储写入速率在9 MiB/s以上,可实现对教学资源数据库快速安全存储。The application effect of the current system in the secure storage of teaching resource databases,not only is the data storage write rate slow,but also the data storage security factor is low.Therefore,this article proposes a design of a teaching resource database secure storage system based on homomorphic encryption.Firstly,the selection of data converters and data memory has been optimized in terms of system hardware.Secondly,in terms of system software,homomorphic encryption technology is used to generate data keys,which are encrypted and stored in a database for teaching resource data.Finally,conduct experimental verification.Experimental results have shown that the designed system has a data storage and write rate of over 9 MiB/s,which can achieve fast and secure storage of teaching resource databases.
