Credible DCS upper computer credible data verification method, system and device and storage medium

The invention belongs to the technical field of industrial automation, and discloses a trusted DCS upper computer trusted data verification method, system and device and a storage medium, and the method comprises the steps: detecting whether a current upper computer is in a safe and trusted state, and building a link between the current upper computer and a requester; after the current upper computer establishes a link with the requester, establishing a TLS encryption transmission channel between the current upper computer and the requester; when the TLS public key of the TLS encrypted transmission channel is verified to be correct, a request that the transmission requester can verify the TLS public key is sent to the requester; receiving and decrypting the encrypted credible verification information sent by the requester to obtain a host name and a credible verification state of the requester; and when the requester is a trusted device and the requester is in a trusted state, sending a data transmission requ
