摘要
针对测控计算机对数据加密存储及存储单元小型化的需求,采用国产PSOC芯片FMQL45T900设计了一款集成多种通信接口的加密存储卡。采用逻辑设计的方式实现存储卡对RS485、CAN、1553B接口、网口数据的加密存储;加密算法采用SM4算法实现,该存储卡同时具有时间同步与一键销毁功能。通过实际测试,该存储卡能够满足测控计算机对数据加密存储的需求,且性能稳定。
Aiming at the demand of data encryption storage and miniaturization of storage unit for measurement and control computer,a cryptographic memory card integrating a variety of communication interfaces was designed by adopting domestic PSOC chip FMQL45T900.Logic design was used to realize the encrypted storage of RS485,CAN,1553B interface and network port data;the encryption algorithm was realized by SM4 algorithm,and the memory card had the functions of time synchronization and one-key destruction at the same time.Through actual testing,the memory card can meet the needs of the measurement and control computer for data encryption and storage,and stable performance.
