Design of information encryption storagesystem based on PKI technology

加密存储可以保证信息的安全性,但是加密存储系统的功能和性能无法满足用户的要求,提出了基于PKI技术的信息加密存储系统设计。根据加密存储系统技术架构,设计了信息采集器和加密存储器,完成系统的硬件设计;在软件设计中,利用PKI技术生成了信息的初始密钥,通过在用户权限列表中定义用户的权限控制结构,完成用户权限列表的设定,结合信息加密存储算法设计,实现了信息的加密存储。测试结果表明,系统对信息的加密存储功能满足用户的要求,通过稳定ASII码值和扩大存储空间,提高了系统的性能,从而满足用户要求。

Encryption can ensure the security of information, but the function and performance of encrypted storage system can’t meet the requirements of users. The design and research of information encrypted storage system is put forward based on PKI technology. According to the technical architecture of encrypted storage system, the information collector and encrypted storage are designed, and the hardware design of the system is completed. In the software design, PKI technology is used to generate the initial key of information. By defining the user’s permission control structure in the user’s permission list, the user’s permission list is set. Combined with the design of information encryption storage algorithm, the encrypted storage of information is realized. The test results show that the encryption storage function of information in the system meets the requirements of users. By stabilizing ASII code value and expanding storage space, the performance of the system is improved, thus meeting the requirements of users.
