[0033] Remote operation and maintenance and data exchange methods for equipment industrial control security, such as figure 1 Shown: Include the following steps:
[0034] S100, collecting the operation data during the operation of the equipment through the collection terminal;
[0035] S200, encrypting the operation data at the acquisition end and generating an encryption password, forming an operation data packet after encrypting the operation data, generating pseudo information in the same format as the operation data at the acquisition end, and mixing the encrypted password into the pseudo information to form an uplink pseudo information packet, The encrypted running data packet and the pseudo-information packet carrying the encrypted password are backed up and stored by the acquisition end;
[0036] S300, when exchanging data, first send an uplink dummy information packet added with an encrypted password, the uplink dummy information packet is sent through an explicit com...
