The invention provides a communication processing method and device, and the method comprises the steps: enabling first equipment to determine that the size of a to-be-sent data package exceeds a preset threshold value during data frame transmission, and carrying out the processing of the to-be-sent data package, and obtaining a target data frame; and sending each target data frame to the second equipment in sequence. The second device receives the data frame sent by the first device; performing data verification on each data frame; if the verification is passed, storing the data frame; when it is determined that an end identifier exists in the stored data frames, verifying the integrity of the data frames of the same packet sequence number; and if the verification is passed, the data frames of the same packet serial number are packaged into the target data packet, so that the packet sticking phenomenon can be effectively solved. According to the invention, the to-be-sent data packet is ...

The invention provides a real-time operating system information security protection method, device and equipment and a medium, which are applied to a nuclear power instrument control system. When the method is executed, target data in a real-time operating system are obtained at first, and then at least one security protection strategy is selected based on the target data; the security protection strategy is pre-arranged in a real-time operating system and specifically comprises an encryption protection strategy, a verification protection strategy and a monitoring protection strategy, and finally performing security protection on the target data according to the security protection strategy. Therefore, the security protection strategy is arranged in the real-time operating system in advance, and at least one security protection strategy is selected for the target data, so that security, integrity and availability protection can be performed on the target data, and the effect of protecting ...
