Specifically, the tamper-resistant device is a signature co-processing device installed in a safety I area of the power distribution network; the device is connected with an I area acquisition server, mainly completes signature and signature checking work of a safe I area master station system service message, and logs abnormal events.
After TCP connection is successfully established, the encryption module generates a random number, signs the random number and encapsulates the time tick message when the encryption module applies for the time tick message; the encryption module sends an encryption module time setting application message to the I area acquisition server; after receiving the encryption module time tick application message, the I-area acquisition server forwards the message to the anti-tampering device, the anti-tampering device checks the signature of the encryption module time tick application message, acquires a random number in the message after the signature is successfully checked, signs the random number and a timestamp of the anti-tampering device to obtain a master station initialization time tick message, and then sends the master station initialization time tick message to the terminal side by the I-area acquisition server; if the verification fails, the area I acquisition server terminates the TCP link; after receiving the 'master station initialized time synchronization message', the encryption module checks the signature of the message, feeds back the signature checking result to the I-area acquisition server, and simultaneously updates the time of the encryption module if the signature checking is successful; and the I area acquisition server starts protocol interaction when receiving successful signature verification, otherwise, the TCP link is reset.

(1) the I area acquisition server sends the protocol instruction to be sent to the tamper-resistant device;
(2) the anti-tampering device signs the protocol message and the timestamp by adopting a private key of the anti-tampering device, and then returns the timestamp, the plaintext message and the signature to the acquisition server in the I area;
(3) the I-region acquisition server issues an instruction (timestamp + plaintext message + signature).
After the collecting server receives the message of the terminal, the steps are as follows:
(1) judging whether the message is a tamper-proof message with a signature, if so, calling an SDK interface to forward the message and I P to a tamper-proof device for processing, otherwise, directly processing by the I-area acquisition server;
(2) the area I acquisition server removes the starting ending character when receiving the message without the signature;
(3) the I area acquisition server receives the signature verification result message, removes the starting ending character, and then reads the signature verification result and the failure reason;
(4) the tamper-proof device receives the message with the signature, verifies the timeliness of the message, searches the signature certificate of the terminal according to I P, verifies the signature of the message, and finally returns the signature verification result and the original message to the acquisition server in the I area.
