摘要
为了保障信息化档案的加密性能,应用多混沌映射思想,以企业人资档案为研究对象,提出人资档案信息自动加密系统。设计加密系统整体架构,其中加解密控制模块由用户交互单元、加解密单元、编解码单元、数据库交互单元等构成。密匙管理模块将混沌序列作为加密序列生成混沌密匙,并设为多级密钥管理模式。管理证书模块通过兼容Windows平台与Linux平台的证书服务器完成人资档案信息证书管理。系统安全性能测试结果表明系统的密匙敏感性更高,密文的混淆和扩散特性更好,提升了系统的安全性。
In order to ensure the encryption performance of information archives, an automatic encryption system for human resources archives is proposed by using the idea of multi chaotic mapping and taking enterprise human resources archives as the research object. It designs the overall architecture of encryption system, in which the encryption and decryption control module is composed of user interaction unit, encryption and decryption unit, codec unit, database interaction unit, etc. The key management module takes the chaotic sequence as the encryption sequence to generate the chaotic key, and sets it as the multi-level key management mode.The certificate management module completes the certificate management of human resource file information through the certificate server compatible with Windows platform and Linux platform. The system security performance test results show that the system has higher key sensitivity, better confusion and diffusion characteristics of ciphertext, and improves the security of the system.
