Embodiment 4

[0115] The present invention provides an embodiment 4 of a security authentication system suitable for the security authentication method described in embodiments 1 and 2, and the system may include:

[0116] an application server, an acquisition device and an authentication device,

[0117] The application server is used to send data instructions to the authentication device for encryption, receive the encrypted data instructions from the authentication device and send the encrypted data instructions to the acquisition device, and receive the encrypted data instructions from the authentication device. The encrypted execution result of the data instruction returned by the acquisition device, and sending the encrypted execution result of the data instruction to the authentication device for decryption, receiving the decrypted execution result of the data instruction by the authentication device,

[0118] The acquisition device is used to receive and decrypt the data instruction...

Embodiment 5

[0123] For the security authentication method described in Embodiment 3, the present invention also provides Embodiment 5 of a security authentication system applied to the security authentication method. The system may include:

[0124] an application server, an acquisition device and an authentication device,

[0125] The application server is used to receive the encrypted data command sent by the collection device and send it to the authentication device, receive the decrypted data command from the authentication device and execute the data command and return the data command for execution The result is decrypted by the authentication device, and is also used to receive the encrypted data instruction execution result sent by the authentication device and send it to the collection device,

[0126] The acquisition device is used to send the encrypted data instruction to the application server, and is also used to receive the encrypted data instruction execution result of the ...

Abstract

The invention discloses a safety authentication method, and is used for the heat supply industry control system safety field. The safety authentication method is characterized in that an application server is used to transmit a data instruction to an authentication device for encryption; the authentication device is used for the encryption of the data instruction, and then is used to transmit the encrypted data instruction to the application server; the application server is used to transmit the data instruction to an acquisition device; the acquisition device is used to decrypt the above mentioned data instruction, and is used to execute the data instruction, and then is used to return the encrypted data instruction execution result to the application server; the application server is used to transmit the encrypted data instruction execution result to the authentication device for the decryption; the authentication device is used to receive and decrypt the encrypted data instruction execution result, and then is used to transmit the decrypted data instruction execution result to the application server; and the application server is used to receive the decrypted data instruction execution result. By adopting the safety authentication method, the key exchange problem before the communication can be solved effectively.

Description

technical field [0001] The invention relates to the security field of control systems in the heating industry, in particular to a security authentication method and system. Background technique [0002] The state proposes to ensure the safety of industrial control systems, strengthen industrial control systems in important areas such as nuclear facilities, aerospace, advanced manufacturing, petroleum and petrochemicals, oil and gas pipeline networks, power systems, transportation, water conservancy hubs, and urban facilities, as well as Internet of Things applications, digital cities, etc. Safety protection and management during construction, focusing on strengthening supervision of industrial control systems that may endanger life and public property safety. [0003] At present, most of the control systems in the heating industry adopt public protocols for plain text transmission, and large-scale industrial control equipment is occupied by foreign manufacturers. Once the fi...
