配电智能终端内容安全管理技术研究及应用

Data security management technology research and application for distribution intelligent terminal

针对配电智能终端内容安全管理需求,基于国家电网CA证书系统、AES加密算法、基于角色的访问控制、数据安全删除、消息推送等方法,设计配电智能终端内容安全管理方案,提出按数据类型进行差异化加密处理算法和以随机数据覆盖填充删除文件的数据安全删除算法。实验验证了配电智能终端应用软件安装监控、数据加密存储、数据访问控制、数据安全删除和消息处理及安全认证等功能。测试结果表明,该方案满足配电智能终端内容安全管理需求,具有可行性及应用性。

For the data security management issues in the distribution intelligent terminal,an approach was proposed based on state grid CA certificate system,AES encryption arithmetic,role-based access control model,file delete security and message pushing.And through doing experiments,functions of the new approach on distribution intelligent terminal were validated such as software installation monitoring,data storage after encrypted,data access control,file delete security and message handling with safety certification.Results of experiments show that the proposed method meets the demand of data storage security with strong feasibility and applicability.
