Embodiment 1
[0034] A remote key management method for a network cipher machine, comprising the following steps:
[0035] 1) The host of the remote user terminal is connected to the secret management network port of the cipher machine through a network cable, and the administrator completes the management login of the corresponding cipher machine device by logging in to the IP address of the cipher machine;
[0036] The specific method for the administrator to complete the management login of the corresponding cipher device by logging in to the IP address of the cipher machine is to enter the IP address corresponding to the secret management network port of the cipher machine in the management interface of the remote user terminal, and click the Connect button to connect and log in to the cipher device to be remotely controlled.
[0037] 2) The administrator selects the data function of the remote user terminal, and sends a unique request preparation command to the cipher machine;

Embodiment 2
[0048] The remote key management method of the network cipher machine as described in Embodiment 1, further, in the step 3), the remote key management agent service program performs format check and CRC check on the received data packet of the remote user terminal The specific process is as follows:
[0049] Format verification: The remote key management agent service program performs TLV format verification on the data packets of the remote user terminal. First, it verifies whether the message header conforms to the TLV format. If the message header conforms to the TLV format, it calculates the data length and compares it with the data The data length value carried in the packet is compared, if the comparison result is consistent, the verification is passed, otherwise the data packet is discarded;
[0050] CRC check: Calculate the CRC check value of the data packet and compare it with the CRC check value carried in the data packet. If the comparison result is consistent, the ...
Embodiment 3
[0052] As in the remote key management method of the network cipher machine described in Embodiment 1, further, the path of the remote key management agent service program in the cipher machine is / app / bin / agtd, when the remote user terminal sends a "request" to the cipher machine After the "prepare" command, the cipher machine executes the " / app / bin / agtd&" command to start the remote key management agent service program in the background of the cipher machine. After the data transmission between the remote user terminal and the cipher machine is completed, the cipher machine executes "killall agtd "command to close the remote key management agent service program. The " / app / bin / agtd&" command and the "killall agtd" command are common commands of the linux operating system, which respectively indicate to open a process and close a process. Through the above-mentioned design, the remote key management agent service program can be automatically started or shut down as required. ...
